If you remember mathematics and the order of operations, you remember that addition or multiplication comes first, and then the rest. The correct order of arithmetic operations in mathematics depends on their type and the conditions of the particular example. Knowing the rules of order is necessary because they are the basis for many everyday operations (shopping, measuring) as well as more complex calculations.

Wow!

 
Vladimir Gomonov:
Other (non-decimal) number systems are full of solutions (I checked just in case). In decimal I have a bummer.
6*4=24
 
Yury Stukalov:
6*4=24

Nope

5*5=25

6*6=36

7*7=47

logic is unbreakable... do the math...
