What number do you get if you subtract thirty units from the number 85?
To solve this problem, we'll perform basic subtraction.
Step 1: Identify the minuend and subtrahend.
The minuend (the number from which we are subtracting) is 85.
The subtrahend (the number to be subtracted) is 30.
Step 2: Apply the subtraction formula .
Step 3: Calculate the difference.
Subtract 30 from 85 as follows:
Therefore, the solution to the problem is .
If we have 85 blocks in total, how many blocks will remain if we remove 4 tens and 1 one?
Thirty units means the same as the number 30. In math, units is another word for ones, so thirty units = 3 tens + 0 ones = 30.
When we subtract 30 from 85, we take away 3 tens from the 8 tens, leaving us with 5 tens = 50. The 5 ones stay the same, so 50 + 5 = 55.
Use addition to check! Add your answer to what you subtracted: 55 + 30. If you get back to your original number (85), you're correct!
Yes! The diagram shows base-10 blocks. Count the blocks representing 85, then remove 30 blocks (3 tens). Count what remains to verify your answer.
Remember: subtract FROM means the first number is bigger. 'Subtract 30 from 85' means 85 - 30, not 30 - 85!
