+5× -7= -35 = (-7+-7+-7+-7+-7) and +4×-2 = -8 = (-2+-2+-2+-2)
Step-by-step explanation:
Repeated addition is adding equal groups together. It is simple multiplication. For example, a number which is repeated can be written in form of multiplication. See, this example;
5+5+5+5+5=25, which can be written as 5×5=25
In this case,
+5 × -7 =-35⇒ (-7+-7+-7+-7+-7)⇒(-35)
and
+4×-2 =-8 ⇒(-2+-2+-2+-2)⇒-8
