Ответ:

2+800-10+400-20+100=792+480=1272

Answer 2

To solve the expression, we'll follow the order of operations, which states that multiplication and division should be performed before addition and subtraction. Here's the step-by-step solution:

2 + 2 × 20 × 20 - 10 + 20 × 20 - 20 + 100

First, let's evaluate the multiplication: 2 + 2 × 400 - 10 + 400 - 20 + 100

Next, perform the multiplications: 2 + 800 - 10 + 400 - 20 + 100

Now, let's perform the additions and subtractions in order: 2 + 800 = 802 802 - 10 = 792 792 + 400 = 1192 1192 - 20 = 1172 1172 + 100 = 1272

Therefore, the final result of the expression 2+2×20×20-10+20×20-20+100 is 1272.
