SL 1.1 to 1.8
SL 1.1 Operations with numbers in the form a ×10^k, where 1 ≤a<10 and k is an integer.
SL 1.2 Arithmetic sequences and series. Use of the formulae for the nth term and the sum of the first n terms of the sequence. Use of sigma notation for sums of arithmetic, its Applications and Analysis, interpretation and prediction where a
model is not perfectly arithmetic in real life.
SL 1.3 Geometric sequences and series. Use of the formulae for the nth term and the sum of the first n terms of the sequence
sequences. Use of sigma notation for the sums of geometric sequences and Applications.
SL 1.4 Financial applications of geometric sequences and series: compound interest and annual depreciation, connection with Loans and repayments
SL 1.5 Laws of exponents with integer exponents. Introduction to logarithms with base 10 and e. Numerical evaluation of garithms using technology
SL 1.6 Approximation: decimal places, significant figures. Upper and lower bounds of rounded numbers, Percentage errors, Estimation.
SL 1.7 Amortization and annuities using technology.
SL 1.8 Use technology to solve Systems of linear equations in up to 3 variables, Polynomial equation.
