Multiply to get

#16+75#

Add to get our final answer of

Answer:

#91#

Explanation:

Keep in mind what the order of operations is! Remember:
Parentheses - Exponents - Multiplication - Division - Add - Subtract, starting with Parentheses.

So, in this problem, you would start with #11+4# which is #15#. You would then do multiplication with #5(15)# as there are no exponents and obtain #75#. After this, you can simply add 16 to get #91#!

You could also take #5# and multiply it by #11# and #4# separately to obtain #75# without actually adding #11# and #4#. That would look like #55# (from 511) and #20# (from 54), adding to #75# which is the same as before!
