Step-by-step explanation:

-9 multiply by 7

avaverretkj14.02.2022 05:20Hey there!

-9r

= -9(7)

= -9 + -9 + -9 + -9 + -9 + -9 + -9

= -9 - 9 - 9 - 9 - 9 - 9 - 9

= -18 - 18 - 18 - 9

= -36 - 18 - 9

= -54 - 9

= -63

Thus, your answer is: -63

Fun fact!

2 negatives equals positive

2 positives equals positive

1 negative & 1 positive equals negative

1 positive & 1 negative equals negative

That’s why your result was a negative because you had 1 negative (-9) and 1 positive (7)

Good luck on your assignment & enjoy your day!
