Answer 1

a: \(=216+42-15=216+27=243\)

b: \(=68+210-25=210+43=253\)

c: \(=200-60+16-8=140+8=148\)

d: \(=5+14-2=17\)

e: \(=221-16+2-1=206\)

Answer 2

a) = 216 + 42 - 15 = 258 - 15 = 243

b) = 68 + 210 - 25 = 278 - 25 = 253

c) = 200 - 60 + 16 - 8 = 140 + 16 - 8 = 156 - 8 = 148

d) = 5 + 14 - 2 = 19 - 2 =  17

e) = 221 - 16 + 2 - 1 = 205 + 2 - 1 = 206

f) = 18 - 17 + 6 = 1 + 6 = 7
