Question

Which statement is true about the expression 12-7+3

Answer 1

The value of the equation 12-7+3 is $\boxed2.$

Further explanation:

Commutative property of addition can be expressed as follows,

x + y = y + x

Commutative property of multiplication can be expressed as follows,

$x \times y = y \times x$

Distributive property can be expressed as,

$\boxed{a \times b= \left( {a \times c} \right) + \left( {a \times d}\right)}$

The value of b = c + d

The associative property is defined as a grouping of multiplication, addition, subtraction and division.

Always use the PEDMAS rule to solve the grouping of multiplication, addition, subtraction and division.

Here, P is parenthesis, E is exponents, M is multiplication, D is division, A is addition and S is subtraction.

Given:

The equation is 12 - 7 + 3.

Explanation:

Consider the equation S = 12 - 7 + 3.

In the equation we have two operations one is addition and another is subtraction

Solve the above equation to obtain the value of the equation.

First add 3 and 7.

$\begin{aligned}A&=7 + 3\\&= 10\\\end{aligned}$

Now subtract 9ab from 10ab.

$\begin{aligned}S&= 12 - 10\\&=2 \\\end{aligned}$

The value of S is$\boxed2.$

Hence, the value of the equation 12-7+3 is $\boxed2.$

Answer 2

Answer: a. associate property.

Explanation: Associate property is a grouping in addition and multiply can be switch. But this question it's about the order of operations. It stands for p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract. It can also go left to right. (PEMDAS)

Like this: → $12-(7+3)$

First do parenthesis first.

$7+3=10$

And then subtract left to right.

$12-10=2$

*The answer must be have a positive sign.*

Final answer: $\boxed{=2}$

Have a great day!
