Answer 1

1) -42 + (19) + (-18) = -23 + (-18) = -41.
2) 25 + (-3) + (-47) = 22 + (-47) = -25.
3) -1,6 + (-2,1) + (3,6) = (-3,7) + 3,6 = -0,1.
4) 6,4 + (-10) + (0,3) = (-3,6) + 0,3 = -3,3.

Answer 2

Let's simplify the expression step by step:

-42 + (+19) + (-18) * 25 + (-3) + (-47) - 1.6 + (-2.1) + (+3.6) * 6.4 + (-10) + (+0.3)

Step 1: Deal with parentheses and signs. -42 + 19 + (-18) * 25 + (-3) + (-47) - 1.6 + (-2.1) + 3.6 * 6.4 + (-10) + 0.3

Step 2: Perform multiplication. -42 + 19 - 18 * 25 - 3 - 47 - 1.6 - 2.1 + 3.6 * 6.4 - 10 + 0.3

Step 3: Continue simplifying. -42 + 19 - 450 - 3 - 47 - 1.6 - 2.1 + 23.04 - 10 + 0.3

Step 4: Perform addition and subtraction from left to right. (-42 + 19 - 450) - 3 - 47 - 1.6 - 2.1 + 23.04 - 10 + 0.3 (-473) - 3 - 47 - 1.6 - 2.1 + 23.04 - 10 + 0.3 (-476) - 47 - 1.6 - 2.1 + 23.04 - 10 + 0.3 (-523) - 1.6 - 2.1 + 23.04 - 10 + 0.3 (-524.6) - 2.1 + 23.04 - 10 + 0.3 (-526.7) + 23.04 - 10 + 0.3 (-503.66) - 10 + 0.3 (-513.66) + 0.3 -513.36

So, the simplified value of the expression is -513.36.
