PEMDAS

To use order of operations stands for (Parenthesis, Exponents, Multiply, Divide, Add, and Subtract) the numbers from left to right. Please Excuse My Dear Aunt Sally!

BOMDAS stands for (Brackets, Of, Multiply, Divide, Add, and Subtract) the numbers from left to right.

Ex. 1+8*9÷3

Solutions:

First, you have to multiply and divide numbers from left to right.

[tex]\displaystyle 8*9\div3[/tex]

[tex]\displaystyle 8*9=72[/tex]

[tex]\displaystyle 72\div3[/tex]

[tex]\displaystyle 72\div3=24[/tex]

Rewrite the whole problem down.

Then, add the numbers from left to right.

[tex]\displaystyle 1+24[/tex]

[tex]\displaystyle 1+24=\boxed{25}[/tex]

[tex]\large\boxed{25}[/tex]

The correct answer is 25.
