Full solution

Q. Evaluate:\newline−7+5−(−10)-7 + 5 - (-10)
  1. Addition without negative signs: First, let's add the numbers without the negative signs. So we have 7+5+107 + 5 + 10. 7+5=127 + 5 = 12, and then 12+10=2212 + 10 = 22.
  2. Apply negative signs: Now, we need to remember to apply the negative signs. The expression was −7+5−(−10)-7 + 5 - (-10), which means we have a negative 77 and a negative negative 1010, which is a positive 1010. So, the correct calculation is −7+5+10-7 + 5 + 10.
  3. Final addition: Let's do the addition now. Start with −7+5-7 + 5, which is −2-2. Then, add the 1010. So, −2+10-2 + 10 equals 88.
