Correct the following mathematical expressions. Ensure all equations are formatted correctly.

[tex]\[ 23 \times 39 = 677 \][/tex]
[tex]\[ 23 + 39 = 62 \][/tex]
[tex]\[ 23 \cdot 39 = 777 \][/tex]
[tex]\[ 23 \times 39 = 897 \][/tex]



Answer :

Let's carefully go through each calculation step-by-step to find the correct results:

1. Multiplying 23 by 39:
- When we multiply 23 by 39, the correct result is 897.

2. Adding 23 and 39:
- When we add 23 and 39 together, the correct result is 62.

3. Calculating the product of 23.39:
- Traditionally in a numerical context, the notation "23.39" would be interpreted as a decimal number. However, here we are treating it as [tex]\(23 \times 39\)[/tex], which equals 897.

4. Evaluating the expression within the parenthesis (23 times 39):
- When calculating the expression [tex]\(23 \times 39\)[/tex] within parentheses, the result is 897.

So, the correct step-by-step detailed results for the mathematical operations are:
1. [tex]\( 23 \times 39 = 897 \)[/tex]
2. [tex]\( 23 + 39 = 62 \)[/tex]
3. [tex]\( 23 \times 39 = 897 \)[/tex] for the product 23.39 interpreted as a multiplication
4. [tex]\( (23 \times 39) = 897 \)[/tex]

Therefore, the comprehensive step-by-step solution matches the provided correct numerical answers precisely:
[tex]\[ (897, 62, 897, 897) \][/tex]
