How can you use the properties of operations to evaluate this expression?

18 + 4(28)

1 answer

To evaluate the expression \( 18 + 4(28) \) using the properties of operations, we can follow these steps:

  1. Evaluate the product: According to the order of operations (PEMDAS/BODMAS), we first calculate the multiplication. \[ 4(28) = 112 \]

  2. Add the result to 18: Now we can substitute \( 4(28) \) with 112 and then add it to 18. \[ 18 + 112 = 130 \]

Thus, the value of the expression \( 18 + 4(28) \) is \( 130 \).

To summarize, we used the property of operations that states we should perform multiplication before addition, which allowed us to simplify the expression step by step.
