I want full explanation!! and my ans is +80 but in my book (Smart Maths-7) written -80 .So, how -80 will come​

Answer 1

Answer:

by distributive property

(-8)×7+(-8)×3

(-8)×(7+3)

-8×10

-80

Answer 2

Answer:

-80

Step-by-step explanation:

7 x -8 = -56

3 x -8 = -24

now, (-8) x 7 + (-8) x 3

= -56 + (-24)

= -56 - 24

= -80

minus & minus results into additon but the minus sign persists.
