$\bigstar\Large\boxed{\textnormal{THE ANSWER SHOULD HAVE A POSITIVE SIGN!}}\bigstar$

Step-by-step explanation:

GIVEN:

$\Large\boxed{\textnormal{SUBJECT: MATH}}$

$\Large\boxed{\textnormal{LESSON: ORDER OF OPERATIONS}}}$

15-6÷2-5*(-7)

To use order of operations, stands for (Parenthesis, Exponents, Multiply, Divide, Add, and Subtract) the numbers from left to right. Please Excuse My Dear Aunt Sally!

You can also used BOMDAS stands for (Brackets, Of, Multiply, Divide, Add, and Subtract) numbers from left to right.

SOLUTIONS:

Solve. (Simplify and find the answer.)

First, you have to multiply & divide numbers from left to right.

$\displaystyle 6\div2$

$\displaystyle 6\div2=3$

Rewrite the problem down.

$\displaystyle 15-3-5*(-7)$

$\displaystyle 5*(-7)=-35$

$\displaystyle 15-3-(-35)$

Then, you add & subtract the numbers from left to right.

$\displaystyle 15-3=12$

$\displaystyle 12-(-35)$

Change negative sign to positive sign.

$\displaystyle -(-35)=35$

$\displaystyle 12+35$

Add.

$\displaystyle 12+35=\boxed{47}$

$\Large\boxed{47}$

Hence, the correct answer is 47.
