Where do I insert parentheses to make this number sentence true:
6 X 4 - 2 x 5 + 6 / 2 =16
I have that same problem but mine has to equal to 17 not 16.
To make the number sentence true, you need to insert parentheses in the expression. Let's break down the initial expression first:
6 × 4 - 2 × 5 + 6 ÷ 2
To determine where to insert parentheses, we need to follow the order of operations (also known as PEMDAS or BODMAS).
The order of operations is as follows:
1. Parentheses
2. Exponents (Powers and Roots)
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)
Given the expression:
6 × 4 - 2 × 5 + 6 ÷ 2
Let's add parentheses to achieve a true number sentence:
(6 × 4) - (2 × 5) + (6 ÷ 2) = 16
Calculating the expression within the parenthesis first:
(24) - (10) + (3) = 16
Now, performing the calculations from left to right:
24 - 10 + 3 = 16
Therefore, by inserting parentheses around specific operations, we made the number sentence true.
