PLSSS HELP MEEEEEE​

Answer 1

so in the second step you see how the 18 is a positive

its supposed to be a negative

in the step 1, the part is -(-6)(-3), right?

so the negative symbol outside the negative 6 cancels out the negative, making it a positive number

it becomes 6(-3), which them multiplies into -18

so, i think the explanation is "the person forgot to change the 18 to a negative in the second step"
yea lol i think thats it
