simplify of 24 + of 18 - of 21
Well, I can make no sense of this. Needs to be typed into common math symbols to make sense. What does "+ of" mean?
it is : simplify of 24+of 18-of 21
To simplify the expression "24 + 18 - 21," follow the order of operations (also known as PEMDAS), which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right):
Step 1: Begin by adding 24 and 18.
24 + 18 = 42
Step 2: Subtract 21 from the sum obtained in step 1.
42 - 21 = 21
Therefore, the simplified form of "24 + 18 - 21" is 21.
