I. Resolver los siguientes ejemplos de suma.
1. 6 +(-5) + 9 + 4 = 14
6 - 5 + 9 + 4 = 14
1 + 9 + 4 = 14
10 + 4 = 14
14 = 14
2. 5 + 4 + 8 + (-16) = 1
9 + 8 - 16 = 1
17 - 16 = 1
3. 4 + 2. 5 + 1.4 = 7.9
6.5 + 1.4 = 7.9
7.9 = 7.9
4. -10 -(+10) = -20
-10 - 10 = -20
-20 = -20
5. -2 - 4 - 10 - 2.5 = -18.5
-6 - 10 - 2.5 = -18.5
-16 - 2.5 = -18.5
-18.5 = -18.5
II. Resolver los siguientes ejemplos de resta.
1. 10 - 12 - 10 = -12
-2 - 10 = -12
-12 = -12
2. 23 - 30 - (+4) = -11
-7 - 4 = -11
-11 = -11
3. 8 + 3 - 14 - 2 = -5
11 - 14 -2 = -5
-3 - 2 = -5
-5 = -5
4. 4 -2 - 12 + 14 = 4
2 - 12 + 14 = 4
-10 + 14 = 4
4 = 4
5. 2 - 10 + 4 - 12 = -16
-8 + 4 - 12 = -16
-4 - 12 = - 16
-16 = -16
III. Resolver suma y resta de fracciones.
1. 10/2 - 4 + raiz de 4 = 3
10/2 - 4 + 2 = 3
10/2 - 4/1 + 2 = 3
2/2 + 2 = 3
1 + 2 = 3
3 = 3
2. 1/4 + 5/4 - 10/ 4 = 4
3/2 - 10/ 4 = 4
8/2 = 4
4 = 4
3. 1/4 - 2/3 + 3/2 = 13/ 12
-5/12 + 3/2 = 13/ 12
-5 + 18/ 12 = 13/ 12
13/ 12 = 13/ 12
4. 1/4 - 5/3 = -17/ 12
3 - 20/ 12 = - 17/ 12
-17/ 12 = - 17/ 12
