number sense Edie wanted to subtract 273-188.she began by finding 2-1.what did edie do wrong?
edie needs to start from the ones place then subtract the rest of the problem. simple as pie.
hey everyone i am Tisha an Clukey i am in 5th grade elementary school i am 10 years old and this really helped me a lot thanks so much for the help thanks ms. Sue and Kaitlyn! :]
Edie was not subtracting the ones first
To find the difference between 273 and 188, Edie started by subtracting 2 from 1, which is not correct.
To subtract larger numbers, we need to follow a specific process called borrowing. Here's how Edie should have approached the subtraction:
1. Start from the rightmost digits:
- Subtract 8 (units place) from 3 (units place). Since 8 is greater than 3, borrowing is required. Rewrite the ones place digit as 13 and carry over 1 to the tens place.
2. Move to the next digit (tens place):
- Subtract 8 (tens place) from the carried-over 1 (from the previous step). Since 1 is less than 8, borrowing is necessary again. Rewrite the tens place digit as 11 and carry over 1 to the hundreds place.
3. Move to the next digit (hundreds place):
- Subtract 1 (hundreds place) from 2 (hundreds place). The difference is 1.
Therefore, the correct answer to 273 - 188 is 85.
In summary, Edie made a mistake by attempting to subtract the units place digits before properly borrowing and adjusting the other digits.
