#-3#

#88 - 16 * 5 + 2 - 3#

PEMDAS (the order of operations) is shown here:

The first thing we need to do is multiplication:
#88 - 90 + 2 - 3#

Now add and subtract from left to right:
#-2 + 2 - 3#

#=0 - 3#

#=-3#

#7#

Multiplication takes precedence over addition/subtraction, so we do that first. We get

#88-80+2-3#

Let's now simplify left to right to get

#8+2-3=10=3=7#

Hope this helps!
