Cheat Sheet

  1. Quick Mental Arithmetic -

    Build fluency in addition, subtraction, multiplication, and division by practicing mental shortcuts like breaking numbers into tens and units (e.g., 47 + 35 = 47 + 30 + 5 = 82). According to university math centers, using complements to 10 (e.g., to subtract 27 from 50, add 3 to reach 30, then subtract the remaining 24) speeds calculations and reduces errors. Regular timed drills can solidify these techniques for your cashier test.

  2. Currency Handling & Change Management -

    Master coin and bill values by practicing the "give-back" change method: subtract the purchase from the tendered amount in easy chunks (e.g., for $13.75 from $20, think $20−$3.75=16.25 then subtract $10 for $6.25 total change). Retail standards from the National Retail Federation emphasize counting back change to customers aloud - this builds trust and catches slip-ups. Consistent practice with different denominations ensures speed and accuracy on a cashier assessment test.

  3. Percentage & Discount Calculations -

    Use the formula Discount = Original × (Discount% / 100) and Final Price = Original − Discount to handle sales and markdowns quickly (e.g., 25% off $80: $80×0.25=$20 discount, final price $60). Khan Academy research shows that visualizing these as parts of a whole (25% as one quarter) helps in-depth understanding. Practicing common retail percentages (10%, 15%, 20%, 25%) builds confidence for the cashier exam.

  4. Speed & Accuracy Techniques -

    Implement batching strategies - scan all like items first, then handle special orders - to maintain a smooth flow. According to the Journal of Retailing Education, short timed sessions (e.g., 2-minute drills) improve throughput and reduce slip-ups under pressure. Always double-check totals before finalizing to catch transposition or scanning errors.

  5. Customer Interaction & Error Prevention -

    Adopt the "ASK" mnemonic: Audit your register, Scan items carefully, Keep receipts visible, and communicate totals clearly to customers. Standards from the National Institute of Standards and Technology recommend confirming each step aloud ("Your total is $27.50, cash or card?") to prevent miscommunications and build rapport. This proactive approach minimizes mistakes and elevates customer service performance on a cashier math test.
