How do you evaluate #-61-(-85)#?

Answer 1

We must distribute the #-1#, which is in front of the parenthesis, to the #(-85)#. Remember, we always take care of parenthesis first according to PEMDAS (parenthesis, exponents, multiplication, division, addition and subtraction). Since this will make it positive the new equation is:

#-61+85=?#

Just work out the solution from this point on:

#-61+85=24#

This advice could be useful:

A negative #(-)# and a negative #(-)# equals #(=)# a positive #(+)#.

A positive #(+)# and a positive #(+)# equals #(=)# a positive #(+)#.

A negative #(-)# and positive #(+)# equals #(=)# a negative #(-)#.

A positive #(+)# and a negative #(-)# equals #(=)# a negative #(-)#.
