@Ryuu Hi! Following the order of operations makes simplifying these binomials much simpler. First simplify what is inside the parentheses by adding or subtracting as indicated, and then multiply them together. The use of the FOIL method is more for multiplying binomials with variables, such as #(x+2)(x-5)#.

How do you evaluate #(8+ 2) \times ( 13- 3)#?

When rounding, you look only at the digit to the right of the digit to be rounded. In 56.479 cents, 6 is in the cent (ones) position. The digit directly to the right of the 6 is a 4, so 6 will not be rounded up. 56.479 cents rounded to the nearest cent is 56 cents.

When rounding, you only look at the first digit to the right of the digit to be rounded. In $56.479, the cent value is 6. The digit to the right of 6 is 4, so 6 is not rounded up to 7. $56.479 rounded to the nearest cent is $56.
