✔ 最佳答案
The assumed subtraction:X-68 = 199
X=267
The original subtraction:
267- 03 = 264
Therefore: the correct difference is 264

原題目的正確差是264。

由於個位的3字寫成8, 將十位的0寫成6, 結果算出的差是199, 即正確寫法是：68,
所以正確的差應是199 + (68 - 03) = 264
所以正確的差應是199 + (68 - 03) = 264

the wrong answer = 199
n the wrong minuend = 68
therefore the total should be = 267
then the original minuend = 30
therefore the correct difference should = 267-30 = 237
n the wrong minuend = 68
therefore the total should be = 267
then the original minuend = 30
therefore the correct difference should = 267-30 = 237
