Write an expression to represent: One more than a number.
Answers
Answer: hi
Step-by-step explanation:
Algebraic expressions are useful because they represent the value of an expression for all of the values a variable can take on.
Sometimes in math, we describe an expression with a phrase. For example, the phrase
"two more than five"
can be written as the expression
5+25+25, plus, 2.
Similarly, when we describe an expression in words that includes a variable, we're describing an algebraic expression, an expression with a variable.
For example,
"three more than xxx"
can be written as the algebraic expression
x+ 3x+3x, plus, 3.
But why? Why use math if we can describe things in words? One of the many reasons is that math is more precise and easier to work with than words are. This is a question you should keep thinking about as we dig deeper into algebra.
Different words for addition, subtraction, multiplication, and division
Here is a table that summarizes common words for each operation:
Operation Words Example algebraic expression
Addition Plus, sum, more than, increased by x + 3x+3x, plus, 3
Subtraction Subtracted, minus, difference, less than, decreased by p - 6p−6p, minus, 6
Multiplication Times, product 8k8k8, k
Division Divided, quotient a \div 9a÷9a, divided by, 9
For example, the word product tells us to use multiplication. So, the phrase
"the product of eight and kkk"
can be written as
8k8k8, k.
Answer: Let the number= x
One more than x= x+1 or 1+x
