Let's add and subtract! Remember, each digit in a number has its own place. For example, in 86, the 8 is in the tens place and the 6 is in the ones place. So 86 is 80 and 6. You can also show this with dots: 80 blue dots and 6 green dots make 86. To subtract, count back the dots. To add, draw more dots. Ready to solve these math puzzles?
