Question

-2,43+6,31+(3,21)+0,49+4,87

Answer 1

$-2,43+6,31+(3,21)+0,49+4,87=-2,43+14,88=12,45$

Answer 2

To add the given numbers:

-2.43 + 6.31 + (3.21) + 0.49 + 4.87

First, let's remove the parentheses by adding 3.21:

-2.43 + 6.31 + 3.21 + 0.49 + 4.87

Next, we can add the numbers together:

-2.43 + 6.31 + 3.21 + 0.49 + 4.87 = 12.45

Therefore, the sum of -2.43, 6.31, 3.21, 0.49, and 4.87 is 12.45.
