Compound interest: annual compounding

Patterns

Applicable neurons

• Multiple (x × y)
• Division (x ÷ y)
• x to the a (xª)
• Percentage (X% / 100)
• x + 1
• Rounding to whole hundredths of something
• name into start tag
• delete a period at the end of a sentence
• (-∞, x]
• constant x.xx
• convert hours, minutes and seconds into HH:MM:SS
• character m
• word 56
• Swap first and second words
• get year from date (yyyy-mm-dd)
• convert HH:MM:SS into hours, minutes, seconds
