Write as a mathematical expression the product of 5 and x symbol

Eight more than the product of two and a number x

Write Algebraic Expressions Choose a letter to use as the variable. The expressions we'll be translating are very straightforward. However, expressions never contain equals signs -- adding an equal sign to an expression would turn it into an equation. All rights reserved including the right of reproduction in whole or in part in any form. If the phrasing indicates addition, place a plus sign between the designated variables and constants. Determine whether the problem involves a multiplication or division operation. It indicates the number of times to repeat a as a factor. Each operation has its own cue words, and I've listed them here, with an example for each: Addition Kelley's Cautions Since subtraction is not commutative, be careful to get the order of the numbers right. Question 3. Read, then calculate each of the following. Ask yourself "What is 3 more than the number 7?

When numbers are added or subtracted, they are called terms. If the phrasing indicates multiplication, place the variable you selected directly on the right of the designated number.

In algebra we speak of a "sum" of terms, even though there are subtractions.

the product of x and 5

Michael Kelley. Problem 3. Ask yourself "What is 3 more than the number 7? In Lesson 3in fact, we will see that we use parentheses to separate the operation sign from the algebraic sign.

write as a mathematical expression the product of 5 and x symbol

We are to first subtract 3 and then add 2. The word factor always signifies multiplication. The parentheses mean that we should treat whatever is enclosed as one number.
