5 - 2n
2 x 4 - x = 7x
The way to write that is 2X+5
Let the unknown number be X: -4x-10 = 2 -4x = 2+10 -4x = 12 x = -3 Remember that a minus multiplied by a minus is equal to a plus: -4*-3 = 12
It is: 2*3*7 = 42

In mathematics, the term "product" refers to the result of multiplying two or more numbers together. When you see the phrase "product is plus or minus," it typically means that the result of the multiplication can be either positive or negative, depending on the signs of the numbers being multiplied.

the number is 8 2 times 8 = 16 16 minus 5 = 11
negative read this : "MULTIPLICATION: minus times minus is plus (negative x negative = positive).....minus times plus is minus (negative x positive = negative).....plus times plus is plus (positive x positive = positive) DIVISION: minus divi minus is plus (negative ÷ negative = positive)......minus divi plus is minus (negative ÷ positive = negative).....plus divi plus is plus (positive ÷ positive = positive)"
