what a constant is
a constant is a number
it does not change
it in- or decreases the expression
find the constant:
47+2
the constant is 2
the secret to adding easier
61+97 can be broken up to 60+1 and 90+7
add the ones
add the tens
add them together
now you have the answer
how do multiplication
remember, multiplication is just repeated addition
think of 5x4 as 5+5+5+5
that's all you need to know
the secret to keeping isfeld happy-revealed!
  1. don't talk, just keep your mouth shut
  2. just work on the subject
  3. pay attention
  4. if you don't understand something, don't be afraid to ask
  5. follow these rules
how to model a variable
  1. use 10v -9, as an example
  2. in this case, v can equal 3
  3. replace v with 3
  4. solve 10x3
  5. solve the rest of the equation
  6. congrats
equivalent fractions
1/2 = 2/4=5/10
multiply the denominator and the numerator with the same number
that's all you have to do
Bedmas question
5x4-6+(12+23)
5x4-6+33
20-6+33
14+33
47
how to add with unlike denominators
  1. take the 2 (or more) fractions (2/9 and 5/7)
  2. find the LCM (63, for this one)
  3. make equivalent fractions (remember, what is done to the bottom must be done to the top
  4. add (14/63+45/63)
  5. change it to lowest terms (69/63=1 6/63=1 2/21)
  6. you're done!
how you can convert mixed numbers into improper fractions
  1. you take the fraction (2 5/9 as an example)
  2. multiple the whole number by the denominator (2x9=18)
  3. take that answer (18) and add it to the numerator (18+5=23)
  4. put the new numerator (23) over the denominator (23/9)
  5. you just converted a mixed number into a fraction!
how to do #23 on the number of the day

take the answer to question 21 (2/9, for example) and divide the numerator (top number) by the denominator (bottom number) (in this case, it's 2/9) and that's your answer
