Question

Simplify. 1.567 + 2.345 - 1.83(5) ?

Answer 1

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`.

Answer 2

`-5.238`

Explanation:

Given: `1.567+2.345-1.83*5`.

We first multiply.

`=1.567+2.345-9.15`

Now, just add from left to right.

`=3.912-9.15`

`=-5.238`

The result is a negative number, which is totally possible in mathematics!
