What is the terrible addition of basic arithmetic returning to the bunker? Some cunning symbols, disgusting subtraction and decryption, terrible multiplication table, maddening multiplication, some more cunning symbols, evil division pants and Jin Shimeng, sometimes zero doesn't mean any rough calculation and crazy and cunning symbols.
Desperate score
You have been warned that the most common scores are unpredictable and difficult to calculate. Eavesdropping, brotherhood and least common multiple, virtual sausage and hateful denominator, the war between decimal and calculator, terrible test on ordinary planet, goodbye, don't forget to close the book.

Don't rashly measure the length of the line. Peck, Pam, Pint and Benedict can be used to measure the meters, thrust and the meters at the tip of 10 ton ruler pin of any object. Is the sealed box going well? From squares to the weight of curry stains-why is everyone making a big mistake? Shiny, messy and crumbling street corner blocks are the main points and a matter of principle. How long is your density and why is it out of control?
Find your lucky star-the secret of probability
A forgotten day in the desert, how not to lose your pants before we enter the wonderful world of possibility? The fair front of the game is still the most wonderful thing in mathematics: football lottery, digital table, curry, hamburger, bell and lottery dice, the collision between date and cunning card meteor, and the participation of monkeys making π poisonous snakes with chicken tails.
