This lesson covers basic subtraction in the form of subtracting whole numbers. Students learn to subtract numbers with two or more digits, such as 985 - 47. The first step is to line up the numbers vertically so that the units digits are in the same column. Next, subtract the units digits, the tens digits, and the hundreds digits. When subtracting the units digits, notice that it is not possible to subtract 7 ones from 5 ones, so 1 ten must be borrowed from the tens column, leaving 7 tens and 15 ones. Now, subtracting the units digits, 15 - 7 = 8, subtracting the tens digits, 7 - 4 = 3, and subtracting the hundreds digits, 9 - 0 = 9. So 985 - 47 = 938. Note that the answer to a subtraction problem is called the difference, so the difference of 985 - 47 is 938.

This lesson covers subtracting decimals. Students learn to subtract decimals by first lining up the decimal points, then subtracting the numbers by column. For example, to subtract 9.514 -- 1.6, first line up the decimal points, then subtract the digits the thousandths column, to get 4 - 0, or 4, then subtract the digits in the hundredths column, to get 1 -- 0, or 1, then subtract the digits in units column, by borrowing a 1 from the 9 in the units column (which leaves an 8 in the units column), to get 15 -- 6, or 9, then subtract the digits in the units column, to get 8 -- 1, or 7. So 9.514 -- 1.6 = 7.914.

This lesson covers customary unit conversions. Students learn the following customary units of measurement: inch, foot, ounce, ton, fluid ounce, pint, gallon, yard, pound, cup, quart, and so on. Students also learn to convert from one customary unit of measurement to another using the following conversion factors: 60 seconds = 1 minute, 7 days = 1 week, 3 feet = 1 yard, 16 ounces = 1 pound, 4 quarts = 1 gallon, and so on. Students are then asked to solve problems using conversion factors, such as 18 feet = ____ inches.

Subtracting multi-digit numbers can be a little confusing when the top digits are smaller than the bottom ones. Let's look at regrouping together. It will help!

When we don't have enough of something, we sometimes borrow it. Same in math! When there aren't enough tens (or hundreds, etc) to subtract with, we can borrow (also called regrouping).
