Different Methods Of Subtraction Learn how to solve subtraction problems using different methods such as compensating, decomposing, and comparing. watch a video or read a transcript with examples and explanations of each strategy. Solved examples on subtraction strategies. example 1: use a number line to subtract 20 from 62. answer: first, identify the numbers 20 and 62 on the number line. to subtract 20 from 62 using a number line, move backwards and start counting from one to 20. 20 is the same as the 20. after 20 ones, we get 42.
Different Methods Of Subtraction 3. find the gap between the two numbers. in order to subtract the two numbers, you'll have to visualize the gap between the two numbers and count the numbers in between. [4] for the problem 15 9, visualize a pile of 15 poker chips. remove 9 of them and you'll see that 6 of them remain. therefore, 15 9 = 6. What's the best way to subtract numbers? the answer: any way that works. here are 4 methods that can help you tackle subtraction problems easily.if you like. When children understand the relationship between addition and subtraction they will find it easier to master their subtraction facts. we can do this by introducing children to the think addition strategy – “i know that 3 4 is 7 so 7 – 4 is 3.”. teaching children about number fact families is the perfect way to show this link. To subtract numbers with more than one digit (such as "42−25") use any of these methods, choose the one you prefer: subtraction with regrouping (also called "borrowing") this is the method most people use!.

A number line can be ‘open’ without any numbers already written on it, or ‘marked’ with some or all of the numbers written on already. and children can put their own marks on a number line to help them make sense of the jumps. using a number line in a subtraction like 43 38 you can count backwards from 43. or you can count forwards. When reading subtraction problems aloud, say “minus” for the minus sign and not “take away.”. for example, when you read the problem 6 – 4, say “six minus four” and not “six take away four.”. this helps children think more flexibly about the role of the minus sign and mentally prepares them to understand interpretations other.
