1 00:00:14,410 --> 00:00:24,820 Hi, everyone, and let's complete our previous lecture about SEAL writing and writing operations and 2 00:00:24,820 --> 00:00:31,170 writing formula, and you must know the sequence of operations here. 3 00:00:31,180 --> 00:00:37,120 You will find the order of order of operation executing. 4 00:00:37,780 --> 00:00:49,240 So you will find that multiplication, precede division and division, precede additions and additions, 5 00:00:49,240 --> 00:00:56,280 precede subtraction and subtraction precede logical operations. 6 00:00:57,130 --> 00:01:00,520 So let's take this example. 7 00:01:01,450 --> 00:01:09,790 If you want to follow the stay of execution, the following formula to multiplication, five plus three. 8 00:01:10,870 --> 00:01:17,920 The question is which operation will be executed first? 9 00:01:19,410 --> 00:01:30,960 Multiplication or addition, let's get back to the operation sequence and we will see that multiplication, 10 00:01:32,100 --> 00:01:37,240 a multiplication, precedes addition. 11 00:01:37,740 --> 00:01:49,180 So the first thing will be executed here is to multiply it by five and the result will be. 12 00:01:49,890 --> 00:01:53,070 After that, you will add three. 13 00:01:53,250 --> 00:01:56,670 So the final result will be 30. 14 00:01:59,380 --> 00:02:11,620 In the next example here, do multiplication two, parentheses five plus three, which operation will 15 00:02:11,620 --> 00:02:12,640 be executed? 16 00:02:12,970 --> 00:02:13,510 First 17 00:02:16,030 --> 00:02:22,320 parentheses makes priority for addition. 18 00:02:22,660 --> 00:02:28,780 So the first operation here is additional five plus three. 19 00:02:28,780 --> 00:02:34,170 The result is eight and eight multiplied by two. 20 00:02:34,390 --> 00:02:37,480 So the final result will be 16. 21 00:02:39,190 --> 00:02:44,680 In the next example, you have two parentheses division. 22 00:02:46,280 --> 00:02:52,100 Three Operation Multiplication addition. 23 00:02:53,450 --> 00:03:04,790 And the vision and addition, so first brought to bear on Athersys, the first operation will be five 24 00:03:05,120 --> 00:03:06,320 plus three. 25 00:03:08,140 --> 00:03:09,340 The result is eight. 26 00:03:10,250 --> 00:03:13,010 Multiplied by two. 27 00:03:14,870 --> 00:03:17,150 So the result is 16 28 00:03:19,640 --> 00:03:31,600 divided by two, so the result will be eight added to do so, the result will be 10. 29 00:03:32,810 --> 00:03:43,220 The last example here, you have addition, you have multiplication, division and two parentheses. 30 00:03:43,790 --> 00:03:49,220 So Burroughs's makes priority for its operation. 31 00:03:49,580 --> 00:03:57,590 So the first operation executed here will be five plus three and the result will be eight multiplied 32 00:03:57,590 --> 00:03:58,190 by two. 33 00:04:00,450 --> 00:04:15,120 Multiplied by two, so the result will be 16 and parenthesis makes priority two additions over division. 34 00:04:15,370 --> 00:04:19,560 So two plus two is four. 35 00:04:22,080 --> 00:04:26,190 After that, we can apply the vision. 36 00:04:28,730 --> 00:04:36,500 So 16 divided by four, the result, the final result will be four. 37 00:04:37,290 --> 00:04:38,660 OK, OK. 38 00:04:42,010 --> 00:04:47,140 So what is the result of this equation let's. 39 00:04:49,030 --> 00:04:54,970 Take example and learn how to write this equation using Microsoft Excel. 40 00:05:02,140 --> 00:05:06,880 Let's practice and write this formula plus two. 41 00:05:09,300 --> 00:05:12,300 Division five. 42 00:05:13,780 --> 00:05:18,040 Plus three, the result will be 13. 43 00:05:21,780 --> 00:05:30,720 Next example here to multiply Orbin to parentheses. 44 00:05:35,550 --> 00:05:52,890 Five plus three, and the result will be 16, the third example here to multiply two, parentheses five. 45 00:05:54,550 --> 00:05:55,660 Plus three. 46 00:05:58,100 --> 00:05:58,790 Divided. 47 00:06:00,880 --> 00:06:02,920 But two plus. 48 00:06:04,710 --> 00:06:10,110 Do so here, Division Brisset addition. 49 00:06:11,840 --> 00:06:24,110 So the first operation will be five plus three is eight, eight by two is 16, 16, divided by two is 50 00:06:25,550 --> 00:06:28,370 eight plus two then. 51 00:06:28,370 --> 00:06:30,800 So the final result will be 10. 52 00:06:32,190 --> 00:06:34,050 OK, that's right. 53 00:06:35,250 --> 00:06:35,760 Also. 54 00:06:37,400 --> 00:06:54,350 Two multiplied by two parentheses five plus three divided by two, parentheses two plus two, so here 55 00:06:55,070 --> 00:06:59,050 parentheses makes priority to additions. 56 00:06:59,600 --> 00:07:06,170 So the first thing will be executed here is five plus three. 57 00:07:06,500 --> 00:07:10,130 The result will be eight eight multiplied by two. 58 00:07:10,130 --> 00:07:11,930 The result will be 16. 59 00:07:13,370 --> 00:07:18,120 And Bernath says, makes it a priority to addition then division. 60 00:07:18,140 --> 00:07:25,460 So here two plus two is four, so 16 divided by four. 61 00:07:25,700 --> 00:07:29,410 The final result will be four. 62 00:07:30,650 --> 00:07:31,820 And that for that. 63 00:07:31,820 --> 00:07:32,280 Right. 64 00:07:32,300 --> 00:07:44,930 OK, if you don't understand anything, please let me know and we will discuss it with more detail. 65 00:07:45,080 --> 00:07:46,580 OK, so. 66 00:07:47,950 --> 00:07:53,810 Let's try to solve this equation, what is the result of this formula? 67 00:07:54,250 --> 00:07:55,350 Let's write it. 68 00:07:55,510 --> 00:08:03,430 Let's practice to write it equal, to multiply the parentheses. 69 00:08:04,380 --> 00:08:05,010 Five. 70 00:08:06,420 --> 00:08:08,220 Minus three. 71 00:08:13,720 --> 00:08:15,040 Forward slash. 72 00:08:16,610 --> 00:08:17,960 Two parentheses. 73 00:08:19,630 --> 00:08:21,370 Two plus two. 74 00:08:27,540 --> 00:08:32,290 Bower do minus one. 75 00:08:33,060 --> 00:08:38,760 So what is the result of this equation, presenter? 76 00:08:38,850 --> 00:08:44,550 The result will be minus O point seven five. 77 00:08:45,090 --> 00:08:53,070 The question is, what are the steps executed to give this result? 78 00:08:53,850 --> 00:08:57,210 What is the sequence of operations? 79 00:08:57,540 --> 00:09:05,280 OK, let's track the execution of this equation step by step. 80 00:09:05,790 --> 00:09:12,490 So parentheses gives priority to substraction operation. 81 00:09:13,170 --> 00:09:20,210 So five minus three is the first thing multiplied by two. 82 00:09:20,580 --> 00:09:29,100 So the result will be for this about the first term on the left hand side. 83 00:09:29,910 --> 00:09:43,110 After that parenthesis gives priority to two plus two, the result will be four and four will be powered 84 00:09:43,110 --> 00:09:44,450 by two. 85 00:09:44,700 --> 00:09:47,100 So the result will be 16. 86 00:09:48,510 --> 00:09:53,700 After that division has priority, then subtraction. 87 00:09:53,820 --> 00:10:02,780 So four will be divided by 16 and the result will be O point to five. 88 00:10:03,240 --> 00:10:18,240 After that we will subtract oh point to five from the one and the result will be minus O point seven 89 00:10:18,240 --> 00:10:18,780 five. 90 00:10:19,260 --> 00:10:20,340 That's right. 91 00:10:20,580 --> 00:10:22,620 This execution is right. 92 00:10:25,250 --> 00:10:28,060 Thank you and see you in the next lecture.
