1st we write out 'twice a number z'.2zNow we divide 8 by 2z and the answer is:8 / 2z
8+5=13
13*2=26
26-7=19
19+1=20
20/2=10
10-2=8
100+5=105
105*2=210
210-7=203
203+1=204
204/2=102
102-2=100
4256+5=4261
4261*2=8522
8522-7=8515
8515+1=8516
8516/2=4258
4258-2=4256
Yes, I tested it 3 times with 3 different numbers.
This would be 45.9
