Feb 25, 2017

Because there are no Parenthesis or Exponents we will first process the Multiplication and Division from left to right:

$- 15 \cdot 4 + 12 \div \left(- 3\right) \to$

$- 60 + 12 \div \left(- 3\right) \to$

$- 60 + \left(- 4\right)$

We can now process the Addition and Subtract:

$- 60 + \left(- 4\right) \to$

$- 64$
