Answer 3

Let's solve the expressions step by step:

1. 700 - 50 × 4 + 180

Start by performing multiplication and then addition/subtraction:

700 - (50 × 4) + 180

700 - 200 + 180

Now, perform the addition and subtraction from left to right:

500 + 180

Finally, add the two numbers:

680

So, the result of the first expression is 680.

2. 830 - 75 ÷ 3 × 4 - 50

First, perform the division and then the multiplication:

830 - (75 ÷ 3) × 4 - 50

830 - 25 × 4 - 50

Now, perform the multiplication:

830 - 100 - 50

Finally, perform the subtraction from left to right:

730 - 50

Now, subtract the two numbers:

680

So, the result of the second expression is 680.
