Using Standard Calculators

Using Standard Calculators

Basic Functions

  • Understand how to perform simple calculations like addition, subtraction, multiplication, and division.
  • Understand how to handle fractions, decimals, and percentages.
  • Familiarise with constant function that allows repeated multiplications or divisions.
  • Appreciate the clear entry (CE) function that clears the most recent entry, instead of the whole calculation.

Advanced Operations

  • Get comfortable with square roots and cube roots.
  • Learn how to use exponentiation (power) function, for raising one number to the power of another.
  • Understand usage of factorial button for calculations involving permutations and combinations.
  • Consider use of reciprocal (1/x) function for fraction conversions.

Memory Functions

  • Learn to use the memory store (MS) and memory recall (MR) functions to store and recall numbers respectively.
  • Understand the memory add (M+) and memory subtract (M-) functions to add/subtract numbers to/from stored memory.

Functions Involving Trigonometry and Algebra

  • Familiarise with functions like sine, cosine, and tangent, and their inverses.
  • Understand how to use logarithmic functions (log) and the natural logarithm (ln).
  • Get a grip on how to implement the algebraic method for problem-solving.

Advanced Calculator Use

  • Apply the correct order of operations using brackets.
  • Understand modes of the calculator such as degree and radian modes for trigonometric calculations.
  • Understand scientific notation for handling large or very small numbers.
  • Examine the use of a fraction button for converting fractions into decimals and vice versa.

Note: Practising calculator usage with a diverse range of numerical and algebraic problems can encourage fluency and accuracy in the real world and exam settings.

Finding Relevant Information from Tables

Section 1: Understanding Tables in Finance

  • Tables are a common way of presenting financial data in a structured and organised manner.
  • They allow for a clear visual comparison of different financial figures at a glance.
  • Tables can include various financial metrics such as prices, sales, costs, revenues, or interest rates.

Section 2: Interpreting Financial Tables

  • Start by looking at the column and row headers to understand what the table is about.
  • Take note of any units provided (such as currency or percentage) as they give context to the figures.
  • Be aware of the time frame referenced in the table, it may represent data from over a specific period or at a specific point in time.

Section 3: Finding Relevant Information

  • The relevant information in a financial table depends on what is needed for the task at hand.
  • Determine what the question or task requires, then find the matching data in the table.
  • This might involve reading across a row, down a column, or comparing multiple figures in the table.

Section 4: Critical Assessment of Data

  • Always critically assess the data presented in a table.
  • Consider if the figures are reasonable or accurate, especially if they are estimates or projections.
  • Look out for any anomalies or inconsistencies in the data, as they may indicate errors or important trends.

Section 5: Making Calculations from Tables

  • You may need to compute values such as sums, averages, or rates of change from the data in the table.
  • Tables can help greatly in breaking down complex calculations into simpler steps.
  • Read the table carefully to ensure you're using the correct figures for each calculation.

Section 6: Understanding Context in Financial Tables

  • Consider the broader context when interpreting data from a financial table.
  • For instance, in a table showing house prices, factors such as location, size, and condition of the property could also be significant.
  • Always try to understand the underlying factors affecting the figures in the table.
