#-26#

Explanation:

start by order of operations. #6^2=36#, so now you have:

# 5-36-(-5)#, and anytime you have a minus next to a negative number it becomes positive, so this gives:

#5-36+5#

Now the final step gives #10-36# which equals #-26#

#-26#

Explanation:

Use the order of operations.

There are no expressions inside parentheses (#-5# doesn't count since it's just a number by itself). So, the next step is to solve the exponents.

#5 - color(red)(6^2) - (-5)#

#5 - color(red)36 - (-5)#

Now, all that is left is addition and subtraction. Note: subtracting a negative number is the same as adding the positive form of that number, so we can change the #-(-5)# to a #+5#.

#5 - 36 - (-5)#

#5 - 36 + 5#

#-26#

So this expression equals #-26#.
