Answer 3

To solve the expression 3 + 4(7 * 4) using two different methods, we'll first perform the calculations step by step.

Method 1: Use the Order of Operations (PEMDAS/BODMAS) According to the Order of Operations, we need to perform the calculations in the following order: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

Step 1: Calculate the value inside the parentheses. 7 * 4 = 28

Step 2: Replace the parentheses with the result of the calculation. 3 + 4 * 28

Step 3: Perform the multiplication operation. 3 + 112

Step 4: Finally, perform the addition operation. 3 + 112 = 115

Method 2: Distributive Property Another way to solve the expression is by using the distributive property of multiplication over addition.

Step 1: Distribute the multiplication over the addition. 3 + 4 * 7 + 4 * 4

Step 2: Perform the multiplications. 3 + 28 + 16

Step 3: Perform the addition operation. 3 + 28 + 16 = 47

So, the expression 3 + 4(7 * 4) is equal to 115 using the Order of Operations, and it's also equal to 47 using the Distributive Property method.
