Answer 1

7*10-20=70-20=50
5*5-10=25-10=15
48-10*3=48-30=18
540+300-100=740

Answer 2

7 × 10 - 20 + 5 × 5 - 10 + 48 - 10 × 3 + 540 + 300 - 100

First, let's solve the multiplication and division from left to right: 7 × 10 = 70 5 × 5 = 25 10 × 3 = 30

Now let's substitute these values back into the original expression: 70 - 20 + 25 - 10 + 48 - 30 + 540 + 300 - 100

Now let's add and subtract from left to right: 70 - 20 = 50 50 + 25 = 75 75 - 10 = 65 65 + 48 = 113 113 - 30 = 83 83 + 540 = 623 623 + 300 = 923 923 - 100 = 823

So, the final answer is 823.
