Answer 2

To calculate the expression, follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction):

12.36 * 1.39 + 1.11 * 12.36 - 2.5 * 4.36

Step 1: Perform multiplication first:

(12.36 * 1.39) + (1.11 * 12.36) - (2.5 * 4.36)

Step 2: Perform the multiplications:

17.1824 + 13.7076 - 10.9

Step 3: Perform the additions and subtractions from left to right:

17.1824 + 13.7076 = 30.89 30.89 - 10.9 = 19.99

So, the result of the expression is 19.99.
