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: → [tex]12-(7+3)[/tex]
First do parenthesis first.
[tex]7+3=10[/tex]
And then subtract left to right.
[tex]12-10=2[/tex]
*The answer must be have a positive sign.*
Final answer: [tex]\boxed{=2}[/tex]
Hope this helps!
Thank you!
Have a great day!

The value of the equation 12-7+3 is [tex]\boxed2.[/tex]
Further explanation:
Commutative property of addition can be expressed as follows,
x + y = y + x
Commutative property of multiplication can be expressed as follows,
[tex]x \times y = y \times x[/tex]
Distributive property can be expressed as,
[tex]\boxed{a \times b= \left( {a \times c} \right) + \left( {a \times d}\right)}[/tex]
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.
[tex]\begin{aligned}A&=7 + 3\\&= 10\\\end{aligned}[/tex]
Now subtract 9ab from 10ab.
[tex]\begin{aligned}S&= 12 - 10\\&=2 \\\end{aligned}[/tex]
The value of S is[tex]\boxed2.[/tex]
Hence, the value of the equation 12-7+3 is [tex]\boxed2.[/tex]
