Enter the value of |-7| - |-10|.
پاسخ درست
-3
توضیح
Each pair of bars hands back a size, so the line becomes seven take away ten, and removing a larger amount from a smaller one leaves a result of size three carrying a minus sign. A result of 3 assumes that anything built from absolute values must stay above zero, but the subtraction happens after the bars have finished their work.
