what happened to the -9 in the 2nd line

ahhh, it came back in the third

You can't do that, that is considered "bad form"

Proper way:
(3×8+4^2)-9
= 24 + 16 - 9
= 40-9
= 31

do the second one in the same way, you again have disappearing and reappearing numbers
Secondly, don't forget to place an = sign in front of each new line

6×(10+6)-6^2

=6×16-6^2
=96-36
=60

correct

Thank you!!

Sure, let's go through the calculations step by step.

The first expression is (3×8+4^2)-9.

To solve this expression, we follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

First, we evaluate the exponent: 4^2 = 4 × 4 = 16.

Now, the expression becomes (3 × 8 + 16) - 9.

Next, we perform the multiplication: 3 × 8 = 24.

The expression becomes (24 + 16) - 9.

Next, we perform the addition inside the parentheses: 24 + 16 = 40.

Now the expression becomes 40 - 9.

Finally, we perform the subtraction: 40 - 9 = 31.

So the value of the expression (3×8+4^2)-9 is 31.

Moving on to the second expression: 6×(10+6)-6^2.

Again, we follow the order of operations.

First, we evaluate the parentheses: 10 + 6 = 16.

Now, the expression becomes 6 × 16 - 6^2.

Next, we perform the exponent: 6^2 = 6 × 6 = 36.

The expression becomes 6 × 16 - 36.

Now, we perform the multiplication: 6 × 16 = 96.

The expression becomes 96 - 36.

Finally, we perform the subtraction: 96 - 36 = 60.

So the value of the expression 6×(10+6)-6^2 is 60.

I hope this helps! Let me know if you have any more questions.
