5+(6+7)= 5 + (7+6)?

Question

I don;'t understand this at all??

Answer 1

Addition is what is called associative. It does not matter what order you complete the addition problem you will still get the same answer.

The rules of operation say that what is in the parenthesis is done first.

So 6+7=13 +5=18 is the same as 7+6=13 +5=18

Answer 2

I'm guessing since you didn't give us anything else to work with that you are supposed to identify what property is demonstrated by this equation.

Yes, it is a true statement, but you need to look at what is different from the left to the right side. The part that is different is just the two numbers in parenthesis. 6+7 is the same as 7+6. The mathematical property that allows us to add two numbers in any order is the Commutative Property of Addition.

Everybody talking about the order of operations is probably doing it right, but I don't think that's what you need here. And the person who mentioned the associative property is mistaken. The associative property allows us to rearrange the order of three of more numbers, ex 3 + (4 + 5) = (3 + 4) + 5

Hope this is what you were looking for and if not hope you find your answer somewhere out here. Good luck. :)

Answer 3

To answer this question we have to keep in mind the "Order of Operations" in this case it would be to solve the equation inside the paranthesis:

First start with the left side of the equal sign:

(6+7) = 13 + 5 = 18

Now solve the left side:

( 7 + 6)= 13 + 5 = 18

18 = 18, therefore the statement is true!

If it were 18 = 20 then the statement would be false.

Hope this helps.

Answer 4

This is one of the basic properties of math

Try it: 5 + (6+7) = 5 + (7+6)

6 + 7 = 7 + 6 = 13, right? You always do the function in the parentheses first.

therefore

5 + 13 = 5 + 13

18 = 18

Answer 5

Since both sides contain the same numbers, and all are adding, according to the property of addition [or something], the parentheses do not alter the sum of both sides. Therefore,

5+(6+7) = 5+6+7, and 5+7+6 = 5 + (7+6)

Answer 6

It is true. That's all there is to it.
5+(6+7)=
5+(7+6)=
(5+6)+7=
5+6+7=
(5+6+7)

It is true....don't read it as a solution.... = just means that it is the same.

Answer 7

When working out Maths always remember the meumonic BIDMAS
Brackets
Indices
Division
Multiplication
Addition
Subtraction
This shows the sequence you have to follow when working a sum. In this sum you have Addition and Brackets. In the mneumonic BIDMAS Brackets come before addition so you have to work out the brackets first.

5 + 13 = 5 + 13

Next you work out the additions that are left

18 = 18

This equation is telling you that the total value of 5, 6 and 7 remains the same even when the numbers aew jumbled up.

Answer 8

18

Answer 9

The sums in the brackets need to be worked out first in any maths equation.

It's 5+13, either way it's the same ... y'see.

Answer 10

Yes,that is all.You are asked if the total after simplification would be the same on both sides of the equation.And the answer is big yes.It is one of the properties of addition
