Let's evaluate the expression step by step:
Expression: 10 - 2 * 7525 : 2150 + 79465 - 3442 * 23
First, clarify the notation: assuming ":" represents division.
Step 1: Perform multiplication and division from left to right
2 * 7525 = 15,050
15,050 ÷ 2,150 = 7
3442 * 23
Calculate 3442 * 23:
3442 * 23 = (3442 * 20) + (3442 * 3) = (68,840) + (10,326) = 79,166
Step 2: Now substitute these values back into the expression:
10 - 7 + 79465 - 79,166
Step 3: Perform the addition and subtraction from left to right:
10 - 7 = 3
3 + 79465 = 79468
79468 - 79,166 = 302
Final answer: 302
Result: 302
