Use the column for the second decimal place
Locate the matching value in the table
Read the probability or area shown in the table
If needed, use symmetry for negative z-scores
If needed, subtract from 1 to find the complementary probability
Check whether the table gives left-tail, right-tail, or area between values
Match your interpretation to the table format
Use the result in your probability or normal distribution calculation
