Adding Integers with the Same Sign

The video tutorial explains how to add integers with the same sign by adding their absolute values and keeping the sign. It introduces the concept of absolute value as the distance from zero and demonstrates addition using counters and a number line. Two word problems are solved: one involving money withdrawal and another about digging a hole, both illustrating the application of negative numbers.
