Sure! Let’s solve each of the 20 integer addition and subtraction problems step by step. Remember:
- Subtracting a negative is the same as adding a positive:
a – (–b) = a + b
- Adding a negative is the same as subtracting a positive:
a + (–b) = a – b

Problem 1:
20 – (–14) – 1
= 20 + 14 – 1
= 34 – 1
=
33
---
Problem 2:
0 – (–16) + 3
= 0 + 16 + 3
=
19
---
Problem 3:
–8 + (–4) + 20
= –8 – 4 + 20
= –12 + 20
=
8
---
Problem 4:
15 + (–11) – (–5)
= 15 – 11 + 5
= 4 + 5
=
9
---
Problem 5:
11 – (–7) + 2
= 11 + 7 + 2
=
20
---
Problem 6:
–7 – 1 – 10
= –8 – 10
=
–18
---
Problem 7:
17 – 8 + (–18)
= 9 – 18
=
–9
---
Problem 8:
–14 – 8 + (–1)
= –22 – 1
=
–23
---
Problem 9:
–16 + (–7) + 15
= –23 + 15
=
–8
---
Problem 10:
20 + 11 + (–8)
= 31 – 8
=
23
---
Problem 11:
–8 + 11 – (–16)
= 3 + 16
=
19
---
Problem 12:
–11 – (–2) + 7
= –11 + 2 + 7
= –9 + 7
=
–2
---
Problem 13:
1 – (–18) – (–9)
= 1 + 18 + 9
=
28
---
Problem 14:
–12 – 15 – 16
= –27 – 16
=
–43
---
Problem 15:
17 – (–20) + 4
= 17 + 20 + 4
=
41
---
Problem 16:
–11 – 15 + (–3)
= –26 – 3
=
–29
---
Problem 17:
18 + (–13) + (–14)
= 5 – 14
=
–9
---
Problem 18:
–20 – 4 + 0
= –24 + 0
=
–24
---
Problem 19:
11 + (–8) + 13
= 3 + 13
=
16
---
Problem 20:
8 + 1 – (–3)
= 9 + 3
=
12
