Reading through these comments thinking, “Did nobody ever learn how to multiply by nine on their fingers?”
Hold up your hands, fingers out.
9x4? Put down your 4th finger. Note there are three fingers to the left of it and six fingers to the right. 36.
9x8? Put down your 8th finger. Note there are seven fingers on the left, two on the right. 72.
9x17? Put down your 17th finger. Zoo called. Time to go home, buddy.
