In this case we want to apply this formula to the entire E column so that all the values in the B and C columns are divided like we see with the single formula. Fortunately learning how to make excel formulas for columns is easy as Excel will automatically change the formula to calculate the new values.
Drugs, for example, sedative/hypnotics (drugs that promote sleep), neuroleptics (drugs used to treat psychosis), minor tranquilizers (drugs that produce a calming effect), stimulants (drugs that increase activity), and antihistamines (drugs used to treat symptoms of allergy) can cause sleepwalking.
