0.0357 has three significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
The way you have done for the question is just fine.
To dial Cyprus from abroad, e.g. from the UK, you dial 00357 Within Cyprus there are separate area codes, e.g. Nicosia = 22 So to dial Nicosia from the UK, the number must start with 0035722 - - - - - -
Hi, My daughter had the most amazing hair straightening treatment (I believe it was this one) at Carrie'l in Edmonton, Alberta. Christina is the stylist that we had. Very expensive, but very worth it. My daughter had ultra thick, extra curly hair below her shoulders. It is smooth, straight, not frizzy and NOT damaged! She has had this treatment twice now (7 months in between appointments).
