Use number properties to simplify the following expression.

-5 + (5 + 3)

in the box below, show each step in simplifying the expression and explain which property you used in each step.
i already have
-5 + 5 + 3
5 + 3 = 8:
8 - 5
8 - 5 = 3
3
but i need to know what properties are used in this answer.

This is 6th grade math. lucky for you i'm a 7th grader the answer is: 3
HOW:
5+3=8
8+(-5)=3
BOOM
Solve the parenthesis. (5+3) is 8. so the problem is simplified to -5+8. and the answer to that is 3
So,

-5 + (5 + 3)

Add 5 and 3 in the parentheses.
-5 + (8)

Now add the numbers.
3
Simplify the following:
-5 + 5 + 3

5 + 3 = 8:
8 - 5

8 - 5 = 3:
  3
Number Properties: PEMDAS

 - 5 + (5 + 3)

1. Parentheses
 - 5 + (7) \\
There Are No Exponents, Multiplication, Division, Or Addition

2. Subtraction

–5 + (5 + 3) = 3

Solution:

Given expression is –5 + (5 + 3).

Using commutative property of addition: a + b = b + a

–5 + (5 + 3) = –5 + (3 + 5)

Using closure property of addition: a + b = c, any number.

–5 + (3 + 5) = –5 + 8

Using commutative property of addition: a + b = b + a

–5 + 8 = 8 – 5

Using closure property of addition: a + b = c, any number.

8 – 5 = 3

–5 + (5 + 3) = 3

Hence –5 + (5 + 3) = 3.

I’m pretty shire it’s 3


Step-by-step explanation:-5+(5+3)

-5+8

3

I would say pemdas

Parenthesis

Exponents

Multiply

Divide

Addition

Subtract

Do the parenthesis first and then add negative five

You would do 5+3 which will equal 8

-5+8

8-5

The answer is 3 hope this helps

3

Step-by-step explanation:

so use PEMDAS for this, you always do parenthesis first so (5+3) = 8+-5= 3

-5 + 5 + 3 = 3
to get rid of the parenthesis distribute the positive
