Answer 2

It seems like you've provided a series of mathematical expressions. Let's break down each expression step by step:

1. (-5.8 + 4.81) * 0.14: First, calculate the sum inside the parentheses: -5.8 + 4.81 = -0.99. Then, multiply the result by 0.14: -0.99 * 0.14 = -0.1386.

2. 1.5 * 3.1 - 2.635: Multiply 1.5 and 3.1: 1.5 * 3.1 = 4.65. Subtract 2.635 from the previous result: 4.65 - 2.635 = 2.015.

3. 14 * (-4) + 836: Multiply 14 and -4: 14 * -4 = -56. Add 836 to the previous result: -56 + 836 = 780.

4. (63 - 84) / (14 - 21): Perform the subtractions inside the parentheses: 63 - 84 = -21 and 14 - 21 = -7. Divide -21 by -7: -21 / -7 = 3.

Combining all the results: -0.1386 + 2.015 + 780 + 3 = 784.8764.

So, the final result of the given mathematical expressions is approximately 784.8764.
