Add ten units to the number 72.
What is the resulting number?
To find the resulting number when ten units are added to 72, we will perform the following steps:
Let's perform the calculation:
Therefore, the resulting number when ten units are added to 72 is .
If we have 85 blocks in total, how many blocks will remain if we remove 4 tens and 1 one?
Because 10 has a 1 in the tens place and 0 in the ones place. When you add 72 + 10, you're really adding (70 + 2) + (10 + 0) = 80 + 2 = 82.
Just increase the tens digit by 1! For 72, the tens digit is 7, so it becomes 8, giving you 82. The ones digit stays the same.
Use subtraction to check addition! If 72 + 10 = 82, then 82 - 10 should equal 72. Since it does, your answer is correct!
Yes! Adding 10 to any number just increases the tens place by 1. For example: 345 + 10 = 355, or 1,267 + 10 = 1,277.
The answer is still the same! Addition is commutative, which means 72 + 10 = 10 + 72 = 82. Order doesn't matter in addition.
