Mastering Mathematical Equations on the dMAT

The Mathematical Equations section rewards two skills: translating a statement into an equation, and solving that equation quickly and correctly. Neither requires advanced maths.

The maths you actually need

The section stays within a defined range:

• Linear equations
• Systems of equations
• Quadratics

There is no calculus and no calculator. If you can solve for x cleanly and handle a two-variable system, you have the toolkit.

Translation is the real skill

Most errors happen before any calculation — in reading. Build the habit of converting each sentence into symbols as you read it:

• "twice as many" → 2x
• "three more than" → y + 3
• "the total is" → =

Write the equation down before you solve. A translated equation is half the answer.

Speed habits that compound

1. Estimate first. If the answer should be near 40, an option of 400 is out immediately.
2. Substitute options when solving is slow. For single-choice questions, plugging in a candidate answer is often faster than isolating the variable.
3. Keep your working legible. Most silly mistakes are copy errors, not maths errors.

The candidates who score highest here are not faster at arithmetic — they are faster at setting up the problem.

Practise translation under time pressure in the Core Module, then confirm your speed with a timed mock.
