Steven is playing an online video game

At the beginning of his turn, he has a
score of -150 points. At the end of
his turn, he has –50 points. How man
points did Steven gain or lose durians
his turn?

Answer 1

Steven gained 100 points.

To calculate the gain or lose of any 2 numbers, always do

Final - Initial

So,

-50 - -150

Is like saying

I have negative 50, and I take away negative 150.

Taking away negative numbers is just addition.

-50 + 150 = 100
