the product of 8 and the sum of 10 and -7
multiply by one if ur looking for the sum and divide by one if look ing for the product, easy
The product of a sum and a difference with 31 times 29 is:(30+1) x (30-1)sum to differencemakea product= 30² - 1²= 900 - 1= 899
The expression xy + z represents the sum of the product of x and y with the value of z. This is a simple algebraic expression where x and y are variables representing numbers, and z is a constant value. To find the result of xy + z, you would first multiply x and y, and then add the value of z to the product.
Equation, not expression. A and B are two numbers. (A + B)2 = A2 + B2 + 2(AB) ----------------------------------
It is when the answer, when 2 things are multiplied, is the same as when they are added. For instance, 2*2=2+2
