compatible numbers mean , for example, 56 x 8. if you wanna find compatible numbers to make the problem easier, then see what 56 is close to. its close to 70, so 70 x 8 would be 560.
use compatible numbers to estimate each difference 84-36
We learn math using numbers because that is math. Also when you get to a higher level in math it is easier to use numbers to write 4,137,985,034.152 than splleing it out.
