FAQ

Everything you need to know about this question

What does 'add 5 units' mean exactly?

+

Adding units means you're putting more of something together. Think of it like having 45 blocks and adding 5 more blocks - you end up with 50 blocks total.

How do I know if I should add or subtract?

+

Look for key words! Words like 'add', 'plus', 'combine', or 'total' mean addition. Words like 'subtract', 'take away', or 'difference' mean subtraction.

Can I use my fingers to check this?

+

Absolutely! Start at 45 and count up 5 more: 46, 47, 48, 49, 50. This counting method is a great way to verify your addition.

Why is the answer 50 and not 40?

+

When you add numbers, the result gets bigger, not smaller. Since 45 + 5 = 50, and 50 is greater than 45, this makes sense for addition.

Is there a faster way than counting?

+

Yes! Since we're adding to the ones place (45 + 5), just add: 5 + 5 = 10. Write down 0 and carry the 1, so 4 becomes 5, giving us 50.
