level (4024)
,Order of Operations:
• The order of operations follows the BODMAS rule:
• Brackets
• Powers Of
• Divide
• Multiply
• Add
• Subtract
,Standard Form:
• The number a x is in standard form when
1≤ a < 10 and n is a positive or negative integer.
Eg:
• 2400 = 2.4 x
• 0.0035 = 3.5 x
, Significant figures:
Example;
• 8064 = 8000 (correct to 1 significant figures)
• 8064 = 8100 (correct to 2 significant figures)
• 8064 = 8060 (correct to 3 significant figures)
• 0.00508 =0.005 (correct to 1 significant figures)
• 0.00508 = 0.0051 (correct to 2 significant figures)
• 2.00508 = 2.01 (correct to 3 significant figures)
