34 + 52 First, break the numbers into their values of tens and ones. This is called expanded notation. 34= 30 + 4 52= 50 + 2
34 + 52Next, add the tens. Then, add the ones.30 + 450 + 280 + 6
34 + 52. Once you have the sums of the tens and ones places you can write the standard form of the number.30 + 450 + 280 + 6 = 86
This is how the problem may look when written by your child: 34 34 + 52+52 30 + 450 + 2 80 + 6 = 86
