2. draw the arch mark at each end of the base line
4. put a dot were both arch marks intersect
5. draw a line connecting the triangle

So for number one, you would have to divide the number by the one being multiplied. I’ll do the first one and you can do the second one, comment if you need help.
(4)*_=-12 —> -12/4 = -3
Check : -3*4 = -12
The answer would be -3.
For the second one, multiply all the numbers first and find the actual answer.
(4)*(-7)*(-1) —> 4 * -7 = -28 —> -28 * -1 = 28
Then multiply their answers.
Evangelina : (-28)*(-1) = 28
Josh : (4)*(7) = 28
Now check who has the right answer and explain why.
For number three, use the letters and plug in the values that are being given to you.
e —> -e
-e * f = -15
-e * g = 6
f * g = -10
Now solve from there!
I really hope I helped, comment if you have any questions:)
