Tricky math! Can you solve this? If 11+11=4 and 12+12=9 Then 13+13=?

Jean-Charles-Athanase Peltier

Born 22 Feb 1785; died 27 Oct 1845 at age 60.French physicist who discovered the Peltier effect (1834), that at the junction of two dissimilar metals an electric current will produce heat or cold, depending on the direction of current flow. In 1812, Peltier received an inheritance sufficient to retire from clockmaking and pursue a diverse interest in phrenology, anatomy, microscopy and meteorology. Peltier made a thermoelectric thermoscope to measure temperature distribution along a series of thermocouple circuits, from which he discovered the Peltier effect. Lenz succeeded in freezing water by this method. Its importance was not fully recognized until the later thermodynamic work of Kelvin. The effect is now used in devices for measuring temperature and non-compressor cooling units.«[Image: Peltier's atmospheric electricity gauge.]

Britney and Christina Work Together

Britney Spears and Christina Aguliera were building a barn. While putting up the inside wall, Britney noticed that Christina was tossing every other nail into the garbage can.

Britney asked Christina, "Why are you throwing those nails away?"

Christina said, "The pointed end is on the wrong end of the nail."

Britney said, "Well, don't throw those away, we can use those on the outside wall!"
