Maths

• To find a fraction of an amount you divide by the denominator and times by the numerator.
• To find the decimal of a percentage you move it left twice.
• Standard form has to be less than 10 and the indicie has to be an integer.
• Anything to the power of 0 is 1.
• The addition rule you just add the indicies and the base always stays the same. EG: 2*3 times by 2*7 = 2*10.
• The subtraction rule means you just subtract the indicies and the base stay as the same.
• (3*6)*2 This is the brackets rule you just times the indicies.
• A percentage is out of 100.
• To decrease a number you take it away from 100 or the biggest number then turn it into a decimal then times it.
