Given the mathematical sentence 3×24÷4-2+5=clearly state the letter meanings of the concept and hence determine the value to the problem using the tree diagram procedural approach.?

In the mathematical sentence 3×24÷4-2+5, the letters represent the following concepts:
- 3: Multiplication
- 24: Multiplication
- 4: Division
- 2: Subtraction
- 5: Addition

Using the tree diagram procedural approach, we can break down the problem step by step:

1. 3×24 = 72
2. 72 ÷ 4 = 18
3. 18 - 2 = 16
4. 16 + 5 = 21

Therefore, the value of the mathematical sentence 3×24÷4-2+5 is 21.

Letter Meanings of the Concept:

- Multiplication: × or ·
- Division: ÷ or /
- Addition: +
- Subtraction: -
- Parentheses: ( )

Working of the Tree Diagram:

- Start with the first operation, which is multiplication (3 × 24).
- Draw two branches, one for each possible result (6 or 72).
- Continue the tree diagram until you reach the final operation and result.

Final Result:

As you can see from the tree diagram, the value of the expression 3 × 24 ÷ 4 - 2 + 5 = 4.
