Higher Order Thinking See Guy's work.

Answer 1

I don’t know where the 55s came from but I’m guessing it is part of the math problem. But the mistake is that the numbers 8,210 and 7200 do not subtract together. They are multiplied. They are multiplied together because of the parenthesis that surrounds each number after Subtraction or Addition. The only way they would be added or subtracted together is if there is an addition or Subtraction symbol between the parenthesis of both numbers. Continuing on,(8,265-55)(7,145+55) will turn into:(8,200)(7200)
Multiply them together will get 59040000.
