Example 3 It is known that 12345 – 5432 + 135 – 24 – (–67) = 7091. What is the value of the expression 12345 – 5432 + 135 – 24?We notice that (–67) is in bracket So, first we open the bracket and then put it to the right side Solving 12345 – 5432 + 135 – 24 – (–67) = 7091 12345 – 5432 + 135 – 24 + 67 = 7091 Putting 67 on right side, 67 gets subtracted 12345 – 5432 + 135 – 24 = 7091 – 67 12345 – 5432 + 135 – 24 = 7024 Hence, required value is 7024
