Explanation :
79+9 =88        152-10 = 142
88+11 = 99     142-12 = 130
99+13 = 112

Explanation :
17+2^2+1 = 22
22+4^2+3 = 41
41+8^2+5=110
110+16^2+7 = 373

Explanation :
206+13 = 219
219+21(13+8) = 240
240+ 29(13+16) = 269
269+37(13+24) = 306

Explanation :
5*5-5 = 20
20*7-10 = 130
130*9-15 = 1155
1155*11 – 20 = 12685

Explanation :
86*0.5+(3*1) = 46
46*0.5+(3*3) = 32
32*0.5+(3*5) = 31
31*0.5+(3*7) = 36.5

Explanation :
2*0.5*1+1 = 2
2*1*2+2 = 6
6*1.5*3+3 = 30
30*2*4+4 = 244
244*2.5*5+5 =3055

Explanation :
650/0.5 +2 = 1302
1302/0.5+8 = 2612
2612/0.5+32 = 5256
5256/0.5+128 = 10640

Explanation :
97*1+2 = 99
99/2-4 = 45.5
45.5*3+6 = 142.5
142.5/4-8 = 27.625
27.625*5+10 = 148.125
