Answer 1

The result of the expression 123 x 12/3 + 78 - 123 is 447.

Step-by-step explanation:

To solve the expression 123 x 12/3 + 78 - 123, we need to follow the order of operations, which is also known as PEMDAS.

PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

In this expression, we first perform the multiplication: 123 x 12 = 1476.

Then, we divide by 3: 1476/3 = 492. After that, we add 78: 492 + 78 = 570.

Finally, we subtract 123: 570 - 123 = 447. Therefore, the result of the expression is 447.
