Question

-39 into 99
Solve using property

Answer 1

-39 [ 100 - 1 ]= -3900 - [-39]
= -3900+39 = -3861
property is distributive property

Answer 2

Below are the distributive property for real numbers-

Let a, b, c are real numbers, then

a(b - c) = ab - ac

= a * b - a * c

= ab - ac

So that -39*(100-1)=(100-1)*(-39)

= -3861
