Order of mathematical operations
If you find the one line of a mathematical equation, subtract, multiply and divide
Why are first calculated?
1 - between brackets ()
2 - Wallace
3 - multiplication and division
4 - addition and subtraction
If found multiplication and division with some being the first from the north to the right
Example
(3 +2) ^ 2 * 5/25 +3 =????
Conducting the operation in the agreed order
5 ^ 2 * 5/25 +3 =
25 * 5/25 +3 =
125/25 +3 =
5 +3 =
8
Another example
5 * 5/25 * 2 ^ 2 * 10/2
In the same way also from the north to the left and Wallace first
5 * 5/25 * 4 * 10/2
25/25 * 4 * 10/2
1 * 4 * 10/2
4 * 10/2
40/2
20
2.5 / 2
1.25
