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 .
Add fifty units to the number 31.
What is the resulting number?
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!
