Respuesta :

Two groups:

(4+2)+5
or
4+ (2+5)

Adding it would get you 11

Answer:

We can use the associative property of addition to group the numbers for addition.

Step-by-step explanation:

We are given the following information in the question:

We have to add [tex]4 + 2 + 5[/tex] in two different ways.

Associative property of addition

  • The associative property states that you can add regardless of how the numbers are grouped.
  • By grouped we mean how we use parenthesis.
  • [tex](a+b)+c = a+(b+c)[/tex]

Working:

[tex]4 + 2 + 5[/tex]

[tex](4+2)+5 = 4+(2+5)\\6 + 5 = 4 + 7\\13 =13[/tex]
