write 3 different ones numbers you could add to 15 without needing to regroup
1, 2, 3, 4
Sure! Here are three different one-digit numbers that you can add to 15 without needing to regroup:
1) 7: 15 + 7 = 22 (no regrouping required)
2) 8: 15 + 8 = 23 (no regrouping required)
3) 9: 15 + 9 = 24 (no regrouping required)
To find three different numbers that can be added to 15 without needing to regroup, we need to consider the place values of each digit. Regrouping or carrying over occurs when the sum of any column exceeds 9.
Let's start by listing the possible single-digit numbers:
1 + 4 + 10 = 15 (no regrouping needed)
2 + 3 + 10 = 15 (no regrouping needed)
5 + 5 + 5 = 15 (no regrouping needed)
So, three different numbers that can be added to 15 without needing to regroup are 1, 4, 10; 2, 3, 10; and 5, 5, 5.
6+9=15
8+7=15
5+10=15
