Question

Write the mathematical expression of the sum of 27 and a number N?

Answer 1

Hint: The best way to approach the word problems is to “divide and conquer” method. In this method, break the problem down into smaller bits and solve each bit at a time. First, we need to translate the word problem into an equation with variables. Then, we need to solve the equation to find the solution to the word problems.
Steps to solve the algebraic word problem:
• Define a variable
• Write an equation using variables by divide and conquer method.
• Solve the equation.
• If a variable is not the answer to the word problem, use the variable to calculate the answer.

Complete step by step answer:
In this question, the word problem is given as “the sum of 27 and a number N”.
In the problem sentence, the word is given as “sum of”. The sum of something is denoted by + in algebra.
The sum of 27 and a number N means that we have to add the number 27 and the number N.
So, we can write the sentence as 27+N.
Hence, the equation of the given word problem is 27+N.

Note: It is important for us to keep in mind how we define our variables. There is often a trade-off between the complexity of what a variable represents and the complexity of the equation.
Some arithmetic operations are as below:
Sum of is something as +.
Difference of is something as -.
Of is something as $ \times $.
Is something as =.
