Dear Mom and Dad,

One thing I learned in module 1 is the order of operations. I learned that parentheses come first. After parentheses come exponents. Then multiplication and/or division, and then addition and/or subtraction. The fraction line means divide.

I also learned about exponents. Any number to the second power (squared ²) means multiply by itself. If anything is to the third power (cubed ³), you multiply it by itself and then the product by the base number. With ten, the exponent is the number of zeros. 10 ³ = 1000 10 ⁴ = 10000 10 ⁵ = 100000

I learned about probability. If there are 10 coins in a bag, and three of them are pennies, there is a 30% theoretical probability of picking a penny.

I also learned about graphing. If both axis on a graph have numbers in them, then you should use a point graph. If both axis have words, then you should use a bar graph.

Sincerely

RJCH
