Question

(-45)
$( - 45) \times 250 \times ( - 4) \times 3$
​

Answer 1

Answer:

135000

Step-by-step explanation:

We can rewrite the question like this

(-45) x (-4) x 250 x 3

we first multiply (-45) x (-4)

2 minuses make a plus or *minus* x *minus* = plus

so that cancels the minus sign.. all we have to do now is multiply all the values

Heres a good rule of thumb .. if you have even numbers of minus signs then all of them will cancel out and give plus for example

-1 x -1 x -2 x -3 x 1

here the first two minuses and the 3rd and 4th minuses cancel and the answer is 6
