Why two negatives equal a positive
In: 3
Imagine yourself on a number line facing the positive numbers. When you take a step back that is like subtracting a number. When you are multiplied by a negative 1, that is like turning 180 degrees. So say I’m at 5 on the number line and I’m subtracting by negative 3, I turn 180 degrees to face the decreasing numbers on the number line and then take 3 steps backwards and end up at 8.
