What is the value of 15 - 3(4 + 2)?

To find the value of the expression (15 - 3(4 + 2)), it is essential to follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

1. Start with the parentheses: Calculate the expression inside the parentheses first:

[

4 + 2 = 6

]

2. Next, handle the multiplication: Now, substitute the result back into the expression, replacing ( (4 + 2) ) with ( 6 ):

[

15 - 3(6)

]

Performing the multiplication gives:

[

3 \times 6 = 18

]

3. Finally, perform the subtraction: Replace the multiplication result back into the main expression:

[

15 - 18

]

When you subtract 18 from 15, you get:

[

15 - 18 = -3
