What is 24 ÷ 2 + 3?

Mathematical expressions are a combination of numbers, variables (like x, y, or z), and operators (like +, −, ×, and ÷) that represent a particular value or quantity. For example, 2+3 is a simple mathematical expression. The + is an operator that tells us to add the two numbers together.

The expression 24÷2+3 is a combination of division and addition operations. Here's how to understand it: Start with the number 24. This is your initial quantity. Then, divide 24 by 2. When you divide 24 by 2, you are splitting the initial quantity into 2 equal parts. Each part contains 12, because 24 can be split into 2 equal parts of 12. So, 24÷2=12. Finally, add 3 to the result. When you add 3 to 12, you are increasing the quantity by 3. So, 12 + 3 = 15.
