You have to simplify the following expression

[tex]6+(7^2-1)+12\div3[/tex]

To solve this calculation you have to keep in mind the order of operations, which is:

1st: Parentheses

2nd: Exponents

3rd: Division/Multiplication

4th: Addition/Subtraction

1) The first step is to solve the calculation within the parentheses

[tex](7^2-1)[/tex]

To solve it you have to follows the order of operations first, which means you have to solve the exponent first and then the subtraction:

[tex]7^2-1=49-1=48[/tex]

So the whole expression with the parentheses calculated is:

[tex]6+48+12\div3[/tex]

2) The second step is to solve the division:

[tex]12\div3=4[/tex]

Now the expression is

[tex]6+48+4[/tex]

3) Third step is to add the three values:

[tex]6+48+4=58[/tex]
