1) aljabar linier
1. 4a + 3a = 7a
2. 8a - 6a = 2a
3. -2x - 4x = -6x
4. 9a - 10a = -a
5. -2x + 7x = 5x
6. 4a + 6 + a + 3 = (4a + a)+(6+3) = 5a + 9
7. -5x + 10 + 3x -9 = (3x - 5x) + (10-9) = -2x + 1
8. 7-8a-a+6 = (-8a-a)+(7+6) = -9a+13
9. 2,7x-1,4x = 1,3x
10. ⅔y + ⅚y = 4/6y + 5/6y = 9/6y = 3/2y

2) penjumlahan dan pengurangan 
1. (6x+2)+(2x-9) = (6x +2x) +(2-9)= 8x -7
2. (5-6x)+(9x-7)=(9x-6x)+(5-7)=3x-2
3. (4/9x - 5/3) + (5/9x + 4/3)=(4/9x+5/9x)+(4/3-5/3) = 9/9x -1/3 = x-1/3
4. (7x+4)-(5x-1) = (7x+4)+(-5x+1) = (7x-5x)+(4+1) = 2x+5
5. (-2y+8)-(3y+6) = (-2y+8)+(-3y-6) = (-2y-3y)+(8-6) = -5y+2
6. (14-a)-(-9-a) = (14-a)+(9+a) = 23
7. (1/4y+6)-(-1/2y-3)=(1/4y+6)+(1/2y+3) = (1/4y+1/2y)+(6+3) = (1/4y+2/4y)+9 = 3/4y+9
