2+(-5 2/5+8:(-1,6)+6-1,3*2)=2+(-5 2/5+(-5)+6-1,3*2)=2+(-5 2/5+(-5)+6-2,6)=2+(-10 2/5+-2,6)=2+(-13)=-11

Answer 2

It seems like there might be a few formatting issues in the expression you provided. I'll do my best to interpret it correctly. Let's break down the expression step by step:

Given expression: 2 + (-5 2/5 + 8/(-1.6) + 6 - 1.3 * 2)

1. Start by simplifying the division: 8 / (-1.6) = -5
2. Calculate the multiplication: 1.3 * 2 = 2.6
3. Add up the rest of the terms: -5 2/5 is equivalent to -5.4 (since 2/5 is 0.4)

Now we have: 2 + (-5.4 + (-5) + 6 - 2.6)

4. Simplify the addition and subtraction: -5.4 + (-5) + 6 - 2.6 = -7.4

Finally, add 2 to the result: 2 + (-7.4) = -5.4

So, the value of the expression is approximately -5.4.
