Question

20×20+281-300+(290×9)

Answer 1

20*20+281-300+(290*9)=400+281-300+2610=2991

Answer 2

20*20=400
400+281-300=381
290*9=2610
2610+381=2991

Answer 3

To calculate the expression:

20 × 20 + 281 - 300 + (290 × 9)

You can follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

First, perform the multiplication inside the parentheses:

290 × 9 = 2610

Now, you can rewrite the expression with the result:

20 × 20 + 281 - 300 + 2610

Next, perform the remaining multiplications and additions and subtractions from left to right:

1. 20 × 20 = 400
2. 400 + 281 = 681
3. 681 - 300 = 381
4. 381 + 2610 = 2991

So, the final result of the expression is 2991.
