A good strategy for adding 9 is to add 10 and take away 1.
Addition and Subtraction (Year 3)
In Year 3, which is the first year in KS2 Maths, you'll learn cool tricks for adding and taking away numbers in Math. It'll make you super confident when you see plus or minus symbols.
Addition is when you put numbers together, like 10 girls + 7 boys = 17 friends at your party! And if you have 20 prizes, you'll have 3 extra because 20 - 17 = 3. See, you just did an addition and subtraction problem! It's helpful in real life too.
