How can you find the difference 120 minece 70 then name the difference. Do you like me
To find the difference between 120 and 70 using mental math, you can follow these steps:
1. Subtract the smaller number (70) from the larger number (120).
2. Let's break down the subtraction mentally:
- Start with the ones place: 0 minus 0 is 0.
- Move to the tens place: 2 minus 7 is -5. However, in mental math, we don't use negative numbers for differences. So, we "borrow" from the hundreds place and add 10 to the -5, resulting in 5.
- Finally, move to the hundreds place: 1 minus 0 is 1.
3. Combine the results from each place value: The difference between 120 and 70 is 50.
In summary, the difference between 120 and 70 is 50.
