Standard form 💙

• Standard form is for writing very long or very short numbers in an easier way
• every standard form must have these 3 things …

  A x 10 n

  A - number between 1 and 10

  x10 - always ‘ x10 ’

  n - must be an interger power
• Adding, subtracting standard form

  
  

  simply split equation and solve the small problems individually, then put together with subtraction or addition symbol, then convert back into standard form if needed
• dividing standard form

  1.separate numbers( x ./. x) from powers (10n ./. 10n)

  2.solve mini equations

  3 then put the 2 answers together

  ( ex. 3x10 to power 4 )
• Multiplying standard form -

  1.separate numbers (n x n) from powers (10 to power of n x 10 to power of n)

  2.work out mini equations

  3.put them together using a ‘ x ‘

  (Ex. 3 x 10 to power 4)
• Power of 0 ( ex. 2 to the power of 0)

  ALWAYS equals 1
• Power of 1 - always itself (2 to power of 1 = 2 )
