2) 42*15-24*15 = 630-360
3) 10*15-10*6 = 150-60
4) 5*18-5*7 =90-35
5) 9*12-3*12 = 108-36
6) 91*7-1*7 = 637-7

Answer 2

Calculation of Expressions

To calculate the given expressions, let's substitute the values and perform the operations:

1) 7*(13-8) - The expression inside the parentheses evaluates to 13-8 = 5. - Multiplying 7 by 5 gives us the result: 7 * 5 = 35.

2) (42-24)*15 - The expression inside the parentheses evaluates to 42-24 = 18. - Multiplying 18 by 15 gives us the result: 18 * 15 = 270.

3) 10*(15-6) - The expression inside the parentheses evaluates to 15-6 = 9. - Multiplying 10 by 9 gives us the result: 10 * 9 = 90.

4) 5*(18-7) - The expression inside the parentheses evaluates to 18-7 = 11. - Multiplying 5 by 11 gives us the result: 5 * 11 = 55.

5) (9-3)*12 - The expression inside the parentheses evaluates to 9-3 = 6. - Multiplying 6 by 12 gives us the result: 6 * 12 = 72.

6) (91-1)*7 - The expression inside the parentheses evaluates to 91-1 = 90. - Multiplying 90 by 7 gives us the result: 90 * 7 = 630.

Therefore, the results of the given expressions are: 1) 7*(13-8) = 35 2) (42-24)*15 = 270 3) 10*(15-6) = 90 4) 5*(18-7) = 55 5) (9-3)*12 = 72 6) (91-1)*7 = 630
