Example:

(–11) + 27 – 15 + 38 + 9 – (–5) + 13 + (–2)

= (–11) + 27 – 15 + 38 + 9 +5 + 13 – 2

[left to right]

= 16 – 15 + 38 + 9 +5 + 13 – 2

= 1+ 38 + 9 +5 + 13 – 2

= 39 + 9 +5 + 13 – 2

= 48 +5 + 13 – 2

= 53 + 13 – 2

= 66 – 2

= 64

(–18) + 31 – (–17) + 12 + 9 – 13 + 15 + (–5)

=

= 48

(–34) + (–27) – 19 + 8 + 12 – (–11) + 13 + (–6)

=

= –42

22  – (–33) + 41 + 9 – 7 + (–18) + 10

=

= 90

(–41) + 13 – (­­–15) + 17 + 19 – (–25) + 44 + (–8)

=

= 84

(–32) + 11 – (–19) + 21 + (–9) – 20 + 26 + (–9)

=

= 7

(–20) + (–17) – 49 + 12 + 51 – (–31) + 19 + (–8)

=

= 19

54  – (–17) + 26 + (–19) – 21 + (–38) + (–16)

=

= 3
