Answer:
-210
Step-by-step explanation:
here, we are adding (-7)+(-7)+(-7) for 30 times.
We Know that multiplication of a number is the repeated addition of the number. For Example, if we multiply X x Y, we are adding X+X+X+.... for Y number of times.
Therefore, we have to multiply -7 with 30, we get:-
-7 x 30 = -210
