Answer:
The answer is 1571.
Explanation:
Using BODMAS. You have to divide first :
81 × (81÷9) + 15 - 2 + 91 × 9 + 1 × 10
= 81 × 9 + 15 - 2 + 91 × 9 + 1 × 10
Followed by multiplication :
(81×9) + 15 - 2 + (91×9) + (1×10)
= 729 + 15 - 2 + 819 + 10
Next is addition and lastly is substraction :
(729+15) - 2 + (819+10)
= 744 - 2 + 829
= 1571
