Exercises in math are rarely particularly pleasurable, especially when the concepts from elementary school have become more complex. Do you have any ideas on how to complete the task without a computer?

Even if it’s not the simplest topic in school, extemporal reasoning is a crucial component of mathematics.

They caused us a lot of headaches, but the fundamentals must never be overlooked. There was a lot of debate online over a third-grade assignment. Few people replied on the internet accurately, and many contradictions appeared.

Which operations should be done first?

– if in an exercise there’s only additions and subtractions, these are performed in the order in which they are written, from left to right.

– if there’s addition, subtraction, and multiplication, the multiplication comes first, then the addition and subtraction.

– if there’s addition, subtraction, multiplication, and division in an exercise, multiplication and division are performed first in the order in which they are written, then the additions and subtractions in the order in which they are written.

– if in an exercise there are round brackets, brackets, and braces, the operations between the round brackets are performed first, then those between the square brackets and then those between the braces.

Additions and subtractions are also solved exactly in the order in which they appear, from left to right.

7 x 6 – 3 x 10+ 18: 9 = 42 – 30+ 2 = 12+ 2 = 14
We performed 7 x 6 = 42, 3 x 10 = 30, 18: 9 = 2
Then 42 – 30 = 12
Finally 12+ 2 = 14

How to solve the exercise?
50 + 10 × 0 + 7 + 2 =?

The first time the second degree operation is performed, ie the multiplication: 10 × 0 = 0

And then the additions and subtractions are performed in the order in which they were written, from left to right.

50 + 0 + 7 + 2 = 59

In the end, the correct answer is 59.
