Multiplying two integers

﻿Hi, I'm Ms. Davis. In this lesson, we're going to be dividing integers. One method for division is the short division method. We're going to calculate 2,682 divided by three. The number that you are dividing goes inside the two lines and the number that you're dividing by goes outside. Two divided by three is zero, with two left over. 26 divided by three is eight, with two remainder. 28 divided by three is nine remainder one. Finally, 12 divided by three is four. This means that 2,682 divided by three is 894. Next, we're going to calculate 7,453 divided by eight. Seven divided by eight is zero remainder seven. 74 divided by eight is nine remainder two. 25 divided by eight is three remainder one. And 13 divided by eight is one remainder five. To complete this calculation, we're going to place a decimal point and a zero. Even with integers, after the decimal point, there can be as many zeroes as you want. We can now write our remainder five. 50 divided by eight is six remained remainder two. I've added another zero. 20 divided by eight is two remainder four. 40 divided by eight is five with no remainder. This means that this is our answer. 7,453 divided by eight is 931.625. When dividing by a two digit number, it is easier to split the number into factors. If we're dividing by 12, we can calculate 4,512 divided by two first. And then divide this number by six. This means that 4,512 divided by 12 is 376. Let's try this a different way. Another factor of 12 is three. So let's divide 4,512 by three. Three multiplied by four is 12. So we're going to divide 1,504 by four. And again, we have got the same answer. Here are some questions for you to try. Pause the video to complete your task and resume once you're finished. Here are the answers. In 2d, the two and four have dots above them to show that the six digits after the decimal three repeat forever. Here are some questions for you to try. Pause the video to complete your task and resume once you're finished. Here are the answers. Riley has carried over at the three, instead of one. The correct answer is 44. In question four, to divide by 14, we can divide by two and then seven, or the other way around. That's all for this lesson. Thanks for watching.
