Question

Simplify (−3.5)(−3)(−6.4).

Answer 1

do you remember the rules for multiplying negative/positive numbers?

negative * negative = positive
negative * positive = negative

so any ideas what three negatives in a row might be? negative or positive?

Answer 2

positive?

Answer 3

no negative

Answer 4

hm. not quite.

notice how the first two are both negative so they cancel out and get a positive #

then positive * negative = negative

Answer 5

Answer 6

so you would then just multiply 3.5*3*6.4 with a calculator then stick a negative sign in front
