I’m supposed to write exactly what i entered in the calculator but i got it wrong and now i’m correcting, i don’t see what i did wrong can someone me

The thing to evaluate:

The thing to type into the calculator: -(-4)+(7)(3)+(-4)^2

Step-by-step explanation:

So I like to put parenthesis around my inputs every single time so I don't go wrong.  You can sometimes get away without doing it but sometimes your calculator will return incorrect value.

Your calculator returned incorrect value because you were suppose to enter instead of .

These values are different. The first is equal to (-4)(-4)=16 and the second is equal to -(4)(4)=-16.

Also if c=-4 then -c=-(-4).

So this is what I would type into my calculator:

-(-4)+(7)(3)+(-4)^2

If you want to perform the order of operations, you do:

1) Parenthesis (grouping symbols)

Notice your parenthesis here don't have any operations to perform.

So move on to the next step.

2) Exponents

You do have this as the end.

3) Multiplication/Division as it occurs left to right

I see the opposite of -4 part and 7(3).

4) Addition/Subtraction as it occurs left to right

yes
