Minus to learn. Here are a few tricks that will help you ace these math problems.
Trick 1
Make 10
2 + … = 7 How can you solve this problem??
Add 10 to 2, 10 + 2 = 12. Then subtract, 12 – 7 = 5.
So 2 + 5 = 7. Is this easy?
A hundred chart is a useful chart, which helps you to be good at subtracting. Here we need to subtract 63 – 35. Find 63 on the chart. You know that 35 has 3 tens and 5 ones. Let’s see:
Start with 63 on the chart, After that go back to 3 tens, and it will move you to 33. After that count back 5 ones, and it will move you to 28.
Now that you know a couple of tricks…why not try solving these?
