Is SAT Math hard for you? Don't worry, many students feel that way. New Digital SAT uses tricky questions that mix different math topics together. This article explains why the test is difficult and helps you solve the hardest questions.
Digital SAT Math section can feel like a formidable hurdle for many students. It is not just about knowing formulas. Many maths questions of Digital SAT require multiple steps to solve. We have mentioned some hardest SAT Math questions with answers.
Question 1: If y = x² + 3x − 4 and y = 2x + 1, what are the solutions for x?
- x= −3
- x= 2
- x = -1±√21 / 2
- x= −3±√29 / 2
How to solve this question:
Set both equations equal:
- x2+3x−4=2x+1x² + 3x - 4 = 2x + 1
- Rearrange: x2+x−5=0x² + x - 5 = 0
- Use the quadratic formula:
x = 1 - √4(1)(-5) / 2
x = -1√21 / 2
Question 2: A population doubles every 6 hours. If the initial population is 1,000, how many hours will it take to reach a population of 8,000?
- 12 hours
- 18 hours
- 24 hours
- 36 hours
How to solve this particular SAT Math question:
- Population after t hours: P=1000⋅2^{t/6}
- Set: 8000=1000⋅2^{t/6}
- Divide: 8=2^{t/6}
- 2^3 = 2^{t/6}
- t/6=3
- t = 18 hours
Question 3:
After a 20% discount, the final price of a jacket is $96. What was the original price?
- $76.80
- $100
- $115.20
- $120
How to solve this type of SAT Math question:
- If 80% = $96
- 0.8x = 96
- x= 96/0.8 = 120
Question 4:
What is the radius of a circle with the equation:
(x+2)² + (y−3)² = 49
- 5
- 6
- 7
- 9
How to solve this type of SAT question:
Here,
- r²=49
- r = √49 = 7
Tips to Ace the SAT Math Section on Test Day
Applicants must be prepared to excel in the SAT Math section on the registered SAT exam date. Here are a few test day tips specifically for SAT Math section for students appearing at a SAT exam centre for the first time:
- Use the Desmos built-in calculator for solving hard questions of SAT, available in the Bluebook App. Helps verify roots, graph functions, and test values.
- Use the Answer Elimination approach if you get stuck on a tricky Math question on SAT. Narrow down your options instead of cold solving and wasting time.
- Plug in simple values in place of variables when you're given expressions, but no clear path.
- Labelling units and underlining key phrases, especially in word problems, will help solve Math problems.
- For topics on percentages, doubling, and fractions, use mental math. Gradually increase your speed of calculation (which is possible through sufficient practice with SAT exam papers)
- Know formulas by heart, especially the following ones, to save time for solving questions:
- Vertex formula
- Area & volume formulae
- Distance, speed and time formulae
- Slope and midpoint
- Exponential forms and equations
- Create mnemonics to remember formulae, equations, and other complex concepts to solve specific questions.

Yes, those taking the Digital SAT exam can use the in-built calculator on the Bluebook App for all Math questions on both the sections of SAT Math. Applicants can also carry a physical calculator in case they feel the need. This feature is only available for Digital SAT format, the previously tested SAT exam (on pen-paper) had one Math module where calculator use was applicable and not for the other one. But on Digital SAT Math section, calculator is allowed for all questions tested on that section. Thus, this is an added advantage for students.
