What number will we get if we subtract 2 tens and 5 units from the number 36.
To solve this problem, we begin by determining what needs to be subtracted from the number 36. We have "2 tens" and "5 units" to subtract:
Therefore, the total amount to subtract is .
Next, we perform the subtraction operation:
Starting with the number 36, subtract 25:
After performing the subtraction, we conclude that the final result is:
.
If we have 85 blocks in total, how many blocks will remain if we remove 4 tens and 1 one?
Place value means each position represents a different amount! 2 tens isn't just '2' - it's actually 20. You must convert to get the true value before combining with units.
No! The problem asks you to subtract 2 tens AND 5 units together as one amount. Think of it as subtracting 25 (which is 20 + 5) all at once from 36.
Think about counting by tens: 10, 20, 30... So 1 ten = 10, 2 tens = 20, 3 tens = 30. Each 'ten' is worth 10 units!
Look for key words! 'Subtract from 36' means 36 is your starting number. You're taking away 25 from it: .
Use addition to check subtraction! If 36 - 25 = 11, then 11 + 25 should equal 36. Try it: ✓
