Reasoning Does (4 + 5) + 2 = 9 + 2? Explain.
(4 + 5) + 2 = 9 + 2 = 11
9 + 2 = 11
Yes. It's a true equation.
To determine if (4 + 5) + 2 equals 9 + 2, we need to follow the order of operations which is known as PEMDAS. PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
In this particular equation, you first need to evaluate the expression within the parentheses, which is 4 + 5. Adding 4 and 5 gives us 9. So the equation becomes 9 + 2 = 9 + 2.
Now, we can combine the two numbers on both sides of the equation. 9 + 2 is equal to 11. Therefore, the equation (4 + 5) + 2 does not equal 9 + 2. It actually equals 11.
So, in conclusion, the statement (4 + 5) + 2 = 9 + 2 is not true.
