What is 78 / 9 x 3 + (6 - 9)?
78 / 9 x 3 + (6 - 9)
78 / 3 + (-3)
26 - 3
23
Note that I did (1/9 * 3) first, due to the fact that 78/9 is not an integer, but 78/3 is.
(78/9)*3 = (78*3)/9 = 78*(3/9) = 78/3
Steve is right it is 23

To solve this problem, we need to follow the order of operations, which is commonly known as PEMDAS. It stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
Let's break down the problem step by step:
1. First, within the parentheses, we have 6 - 9 which equals -3:
78 / 9 x 3 + (-3)
2. Next, we perform the division: 78 divided by 9 equals 8.6667 (rounded to four decimal places):
8.6667 x 3 + (-3)
3. Then, we do the multiplication: 8.6667 multiplied by 3 equals 26 (rounded to the nearest whole number):
26 + (-3)
4. Finally, we add the numbers: 26 plus -3 equals 23.
Therefore, the solution to the equation 78 / 9 x 3 + (6 - 9) is 23.
