How can you use 4s facts to find 7 time 8

So 4's facts

we know that 4 times 2=8 and the associative property of multiplication says
a(bc)=(ab)c

so 7(8) (means 7 times 8) means 7((4)(2)) and associative say we can group them and say (7)(4)(2) so (4)((7)(2)) or 4(14) and 4 times 14=56

7 times 8=56

5 * -2

Everyday, he takes $2, so he's going to be $2 more in debt each day. This means he's going to have -$2 each day.
