The most common math mistakes on the TEAS 7
Fraction arithmetic errors
Always find a common denominator before adding or subtracting. Never add numerators across different denominators directly.
Percentage word problem setup
Identify what the question is asking: “X is Y% of Z” translates to X = (Y/100) × Z. Set up the equation before calculating.
Unit conversion direction
Use dimensional analysis (multiply by the conversion fraction so the original unit cancels). Write out the units explicitly to avoid going the wrong direction.
Mean vs. median confusion
Mean = sum ÷ count. Median = middle value of a sorted list. For even-numbered lists, median = average of the two middle values.
Calculator over-reliance on simple problems
For simple arithmetic, working mentally is faster than entering values into the calculator. Reserve the calculator for multi-step calculations.
