Grade 6 Expressions and Equations - 6.EE.A.2a

Tips for evaluating written expressions - Though mathematics is all about numbers, the algebraic section of mathematics uses letters, words, and expressions to define a problem. In a given word problem, many words play a crucial role in deciphering the answer, but most times, it is challenging to evaluate certain words and expressions. Learning to assess the expressions can make you crack the answer quickly. Let's learn the art of doing it: Replace the letters of expression with the assigned values The first step is to carefully replace the letters of expression with the values assigned in the word problem. Now you have an expression with only numbers in it. Write each value in parentheses. Perform the operations - After substituting the values, now perform the operation in the correct order of the expression. Don't forget to use the correct order of operations. Perform with exponents: Make sure that you consider the exponents too and perform correct mathematical operations. Here's an example of the expression: 2x^2 – x + y, for x = 3 and y = –2. 2(3)^2 – (3)+ (-2), 18 – 3 – 2, The answer is 13.
