Sum of is a grouping symbol.
7*(2+5)
The sum means the result of adding the numbers. Therefore the sum of 20 and 15 is 35. 5 times 35 is 175 - therefore 5 multiplied by the sum of 20 and 15 is 175.
The sum of multiplication expressions is the answer that you'd have, if you added together more than one multiplication expression. For example: 3 x 4 + 5 x 2 = A <--- A = the answer after you do/evaluate the expressions 12 + 10 = A 22 = A 22 is the sum of the above multiplication expressions (i.e. 3 x 4 plus 5 x 2)
5-x-1-2+x= x-7
The sum of two numbers is those two numbers multiplied together. For instance, the sum of 4 and 5 is 20.
In algebra, the term "multiplied with the variable" refers to a coefficient, which is a number or expression that is multiplied by a variable. For example, in the expression (5x), the coefficient is 5, and it indicates that the variable (x) is multiplied by 5. This operation is fundamental in forming algebraic expressions and equations.

1 x 2 x 3 x 4 x 5 x 6 = 720 When they are multiplied they produce a product, not a sum. Addition produces a sum.
-2
-2(x + 9) = -8 -2x - 18 = -8 -2x = 10 x = -5
The sum of two numbers is those two numbers multiplied together. For instance, the sum of 4 and 5 is 20.
10

5 Check the intensity of the object. The sum will be 5.
20 - 5(8 + 2) or you could just write -30
