Standard Form

Standard Form

Converting numbers to standard form
1. The amount of 0's is the number you need to use as a power
  1. e.g 1 000 000 = 1 x 10^6
2. If there is more than one sig. fig. then you need to change the number into a decimal and add on an extra number to the power.
  1. e.g. 540 = 5.4 x 10^2
3. Minus numbers
  1. You times it with a minus power
  2. The amount of 0s after the d.p + 1 is the number for the power
    1. e.g 0. 000 0006 = 6 x 10^-7
    2. e.g 1.36 10^-4= 0.000136
Multiplying Standard Form
1. Multiply the coefficients and add the indices.
  1. e.g (4.5 x 10^4) x (6.45 x 10^5)
    1. 4.5 x 6.45 = 29.025
    2. 4+5 = 9
    3. 29.025 x 10^9
      1. 2.9025 x 10^10
Adding Standard Form
1. e.g (4.5 x 10^4) x (6.45 x 10^5)
  1. Convert the numbers into normal numbers then add
Dividing Standard Form
1. Divide the coefficients and subtract the indices.
2. e.g (8x10^9) / (2x10^3)
  1. = (8/2)x10^(9-3)
    1. 4 x 10^6
Subtracting Standard Form
1. Convert the numbers into normal numbers then minus them
