<h3>________________________________________________</h3>

<u>Step by Step Solution for Part-1:</u>

<u>We know that:</u>

  • The successor of a number defines one to be added to a number
  • The predecessor of a number defines one being subtracted to a number

<u>Solution:</u>

  • ⇒ (-5 + 1) + (6 - 1)
  • ⇒ (-4) + (5)
  • ⇒ 1
<h3>________________________________________________</h3>

<u>Step by Step Solution for Part-2:</u>

<u>We know that:</u>

  • b - 1 = a
  • To solve: a - b

<u>Solution:</u>

  • ⇒ a - b
  • ⇒ (b - 1) - b
  • ⇒ (-b + 1) + b
  • ⇒ -b + 1 + b
  • ⇒ 1
<h3>________________________________________________</h3>

<u>Step by Step Solution for Part-3:</u>

  • (42 - 66) - (100 - 24)
