telephone

Find a calculator

Insert in the first three digits of your phone number (not the area code)
Example  : (905) 567 - 1111

Multiply these three numbers  by 80
567 x 80 = 45360

Add 1
45360 + 1 = 45361

Multiply by 250
45361 x 250 = 11340250

Add to this the last 4 digits of your phone number
11340250 + 1111 = 11341361

Add again the last 4 digits of your phone number.
11341361 + 1111 = 1134272

Subtract 250
1134272 - 250 = 11342222

8. Divide number by 2
11342222 / 2 =  Magic phone number
