You can put this solution on YOUR website!
In a word, no.
5 times 0 is 0, just like you said,
but look at the minus sign in front of the other 5. That sign goes with the 5, not with the 5 + 3. If there had been parentheses around the 5 + 3, as in:
\ =\ 1)
then you would have been correct, but:
9 minus 5 is 4
Then
4 plus 3 is 7
And it really has nothing to do with going from left to right or vice versa, it is simply a matter of keeping the sign together with its term.
You could have finished the calculation thusly:
-5 plus 3 is -2
-2 plus 9 is 7
What might help you in the future would be to write everything as an addition problem. Just forget that the operation of subtraction ever existed:
For this example, re-write thusly:
\ +\ 5\ \cdot\ 0\ +3)
Capisce?
