Question

630+ (740-140)(450+540)+(450-400)900-(120+200)​

Answer 1

Ответ:

630+(740-140)=1230

(450+540)+(450-400)=1040

900 -(120+200)=580

Answer 2

Let's break down the expression step by step:

1. Calculate the innermost parentheses:

   • (740 - 140) = 600
   • (450 + 540) = 990
   • (450 - 400) = 50
   • (120 + 200) = 320

2. Substitute these values back into the expression: 630 + 600 * 990 + 50 * 900 - 320

3. Perform multiplications: 630 + 594000 + 45000 - 320

4. Perform additions and subtractions: 654310 - 320

5. Final result: 654,310 - 320 = 653,990

So, the result of the given expression is 653,990.
