Ten (10)


Because there is a decimal point in the number, you count every number. Even the final two zeros at the end of the number are significant. Here are the rules

  • Every non-zero number is significant
  • Zeros sandwiched between non-zero numbers are always significant
  • If there is a decimal, the zeros between the decimal and the first non-zero number to the left are significant.
  • If there is a decimal, all zeros to the right are significant
  • If there is not a decimal, zeros at the right are not significant
