Adding and subtracting two-digit numbers means working with numbers that have a tens place and a ones place. Place value tells us the value of each digit in a number. For example, in the number 23, the '2' is in the tens place, so it represents 20, and the '3' is in the ones place, representing 3. When adding or subtracting, we start with the ones place and then move to the tens place. Worksheets help us practice this skill by providing structured problems that reinforce our understanding!
