Please help I don’t understand
lesya [120]

Answer:

  • 2·8·7
  • 8+2+7
  • 12·5·3
  • 3+5+12

Step-by-step explanation:

The properties of addition and multiplication allow you to rearrange and/or regroup the components of a sum or a product. That is the point of this exercise.

  (2·8)·7 = 2·(8·7) . . . . parentheses have moved: associative property

  2 + 7 + 8 = 8 + 2 + 7 . . . . order is rearranged: commutative property

  5·3·12 = 12·5·3  . . . . .  order is rearranged: commutative property

  (3 +5) +12 = 3 +(5 +12) . . . . parentheses have moved: associative property

_____

<em>Additional comment</em>

Whenever you're in doubt about the equivalence of numerical expressions, you can use your calculator to evaluate them. They will give the same result if they are equivalent. (You need a good scientific or graphing calculator that uses parentheses for this. Some seriously good calculators are available as low-cost phone apps.)

The Google search box also serves as input to the Google calculator. You can use an asterisk (*) for multiplication.
