what is 3 times 5 -1times10 i need this awnser because im in grade 7 and im stupid so *ye*
Well according the order of operations, multiplication or division (left to right), then addition or subtraction (left to right).
I am assuming you mean this:
3∗5−1∗10
We have the multiplication, you start with that.
15−10
Then we have a simple subtraction problem
5
Hope this helped!
