### SUBTRACT:

**(1)(a) 30 – 20 = 10**

**(b) 20 – 10 = 10**

**(c) 40 – 20 = 20**

**(d) 50 – 30 = 20**

**(e) 10 – 10 = 0**

**(2)(a) 80 – 50 = 30**

**(b) 60 – 40 = 20 **

**(c) 80 – 70 = 10**

**(d) 60 – 50 = 10**

**(e) 90 – 70 = 20**

**(3)(a) 40 – 30 = 10**

**(b) 60 – 20 = 40**

**(c) 70 – 30 = 40**

**(d) 80 – 30 = 50**

**(e) 90 – 20 = 70**

**(4)(a) 90 – 80 = 10**

**(b) 70 – 10 = 60**

**(c) 30 – 30 = 00**

**(d) 40 – 10 = 30**

**(e) 50 – 40 = 10**
