Question

Write 2 pairs of integers whose

Sum is -6

Difference is -9

Solve the following



(-6)×(-5)+(-8)

((-15)×8+15×(-4)),using properties

(-39)÷13

25×((-4)-(-1)) ,using properties

30×103,using proper

(-64)÷(-8×-8)

(-11)×(6)×3

(-4)×(-6)×(-5)

(-39)×40+(-40) ,using properties

((-17)+(-3))÷5

((-28)+(-22))÷(-3+8)

50×(-11)×8×(-6)

Verify that

a×(b+c)= a×b+a×c

,where a= (- 19),b=3,c=(-8)

Verify that a÷(b+c)≠(a÷b)+(a÷c) where a=(-15), b=2,c=1
