The math worksheet focuses on practicing integer addition problems. It contains a series of exercises where students are required to add two integers in each problem. Both positive and negative integers are included. Integers are numbers that can be positive, like 7 or 22, or negative, like -5 or -100. Zero is also an integer. When you add integers, you must pay attention to the signs (positive or negative). If the numbers have different signs (like -15 + 3), you subtract the smaller number from the bigger one (15 - 3 = 12) and keep the sign of the bigger number. For example, -15 + 3 = -12. If both numbers are negative (like -17 + -7), you add them up as usual (17 + 7 = 24), but the answer stays negative, so -17 + -7 = -24.
