#-15#

#4 + 3(-6) - 1#

PEMDAS (the order of operations) is shown here:

The first thing to do is multiplication:
#4 - 18 - 1#

Subtract from left to right:
#-14 - 1#

#=-15#

Hope this helps!

#-15#

Multiplication takes precedence over addition/subtraction, so we can do #3*-6# first to get #-18#. We now have

#4-18-1#

We can work from left to right to get

#-14-1=-15#

Hope this helps!
