Simplifying this expression gives us #-5.238#

Explanation:

So before starting to simplify, you need to remember PEMDAS as it is important for this type of problem.

So we want to start with the parentheses so multiplying 1.83 by 5 like this #-1.85*5# gives us #-9.15#

So we now have #1.567+2.345-9.15#. Now we need to do order of operation. So let add 1.567 and 2.345 together which gives us: 3.912 but we need to subtract if from #-9.25# like this #3.912-9.15# which gives us: #-5.238#.
