Given
Copy numbers with their units.
Ask
Name the final unit or quantity.
Setup
Build the proportion, percent relationship, or conversion bridge.
Check
Estimate whether the answer makes sense.
Most TEAS math you miss isn't an arithmetic problem. You set the equation up wrong before you ever touch the numbers, then blame the calculator. Here's the fix: turn every word problem into four boxes before you calculate anything. Given, Ask, Setup, Check. The first three force you to read the problem correctly, and the last one catches the answers you'd otherwise lock in and lose.
The four-box setup
Fill in four boxes before you calculate. Each one prevents a specific, common mistake.
| Box | What goes there | What it prevents |
|---|---|---|
| Given | Numbers, units, rates, totals, and constraints. | Copying the wrong value into the equation. |
| Ask | The exact thing the question wants, including units. | Solving for the wrong target. |
| Setup | The proportion, equation, or operation before arithmetic. | Guessing based on keywords alone. |
| Check | A unit check and a reasonableness check. | Choosing an answer that cannot fit the story. |
Work the four boxes in order
Write what the question is asking for
Before you calculate anything, write the final unit you need: dollars, milliliters, percent, minutes, tablets, miles, or another quantity. This protects you from solving for the wrong thing. The question usually gives you extra numbers, and the target unit tells you which numbers matter.
Circle the given quantities with their units
A number without a unit is a trap. If the problem gives 3 hours, 180 minutes, 0.5 liters, or 500 milliliters, the unit decides the operation. Copy the quantity and unit together before you start moving numbers around.
Build the relationship before you solve
Write the relationship with labels, not bare numbers, so a wrong setup is obvious on sight. Keep the same unit on top and bottom of each side, and the math falls out.
- Proportion: if 2 tablets hold 250 mg, keep mg over tablets on both sides, so 250 mg / 2 tablets = x mg / 5 tablets gives x = 625 mg.
- Percent: name part, whole, and percent before you multiply, so "15% of 80" becomes part = 0.15 x 80 = 12.
- Conversion: chain the units so they cancel, so 1.5 L becomes 1.5 L x 1000 mL / 1 L = 1500 mL.
If the labels don't line up, the answer won't either.
Check whether the answer is reasonable
The fastest way to catch a bad word-problem answer is a reasonableness check. If a dosage answer is ten times larger than every answer choice near it, or a time answer goes the wrong direction after a speed increase, pause before you choose it.

Common operation traps
You lose points when you pick an operation because one word looks familiar. “Of” usually means multiply in a percent problem, but “20% of what number is 15” isn't multiply-and-done, it's solving backward for the whole (0.20 x n = 15, so n = 75). “Per” signals a rate, but “60 miles per hour for 90 minutes” is asking for distance, not the rate you were handed. The keyword tells you which tool is on the table. Your four boxes tell you whether to use it.
When two answer choices are close, use units to decide. If the question asks for milliliters and your setup leaves you with milliliters per hour, you are not done yet.
Practice in short sets
Ten carefully reviewed word problems are better than fifty rushed ones. For each miss, rewrite the setup without solving it. That builds the habit the exam actually tests: converting words into math under time pressure.
What to do next
Take five word problems today and resist the urge to solve. Fill the four boxes first, then calculate. Watch which box you stall on: if it's Ask, you're misreading the question; if it's Setup, your weak spot is proportions or conversions, not arithmetic. The box that slows you down is the one that's been quietly costing you points all along. That's where the next hour of study goes.
