Mastering addition and subtraction in Year 8 can be made easier with some helpful mental math tips. Here are a few you might like:
Break it Down: This means breaking numbers into smaller parts that are easier to handle. For example, if you want to solve (48 + 27), you can think of it like this: (48 + 20 + 7 = 68 + 7 = 75).
Use Complements: For subtraction, like (100 - 37), try viewing it in a different way. You can think: (100 - 30 - 7 = 70 - 7 = 63).
Number Patterns: Recognizing patterns can be really helpful. For example, when you add multiples of 10, you might notice a pattern that makes it simpler.
Estimation: Sometimes, rounding numbers to the nearest ten can make things easier. For instance, you can estimate (198 + 53) as (200 + 50 = 250).
These strategies can help you do calculations faster and feel more confident in math!
