Understand how signs before integers determine the result: same signs produce a positive, different signs produce a negative, with even negatives yielding positive.
Explore the distinction between rational and irrational numbers, illustrate infinite rational values between 4 and 6, and explain terminating vs non-terminating, non-repeating decimals, and how multiplying rationals and irrationals behaves.
Learn to convert terminating decimals to fractions by counting decimal places, setting the denominator with zeros, and reducing to lowest terms using common factors.
Convert non-terminating repeating decimals to fractions by setting x to the decimal, multiplying by the needed power of ten, and subtracting to solve for x. Simplify to lowest form.
Use exponent rules to simplify expressions with the same base and multiply or divide exponents. Solve for x and m by equating exponents and using base conversions.
Master the order of operations (pemdas) from parentheses to exponents, and from multiplication and division to addition and subtraction, using left-to-right rules for mixed operations.
Master significant figures and past paper problems by estimating expressions from one significant figure conversions and learn decimal and fraction techniques for accurate, quick comparisons.
Multiply and divide numbers in scientific notation using laws of indices to adjust exponents. Convert results to standard form with a number between 1 and 10 by shifting the decimal.
Learn to compute upper and lower bounds by adding or subtracting half the unit for rounded measurements, illustrated with door height, masses, distances, and times.
Apply upper and lower bounds to find x+y, y minus x, and x divided by y limits; determine the shaded area and the smallest p using V and R bounds.
Apply bounds to past paper problems in the number section by computing upper and lower bounds for eggs and hen counts, using nearest ten and nearest twenty adjustments.
