Evaluate Arithmetic Expressions

Statement

Given an arithmetic expression as a string, evaluate its result. For simplicity, let’s assume that there are no parentheses in the expression and only the following binary operations are allowed: (+ $\space$ - $\space$ * $\space$ /).

Examples

Here are a few examples of expressions and their results:

$$2+3=5$$

$$6+4/2*2=10$$

$$3+2.45/8=3.30625$$
