MathFourOps

The 4 arithmetic operations: +, -, *, /, are used very often in our daily lives. In many places, machines do the calculations for us and people forget how important it is to master the operations ourselves. Machines might not make mistakes but humans do. For example, if a shop forgets to update the sale price, you might pay the higher price without noticing unless you have mastered the 4 arithmetic operations.
