How to Study DeltaMath, WebAssign & ALEKS Homework Step by Step (Without Wasting Attempts)
Online STEM homework platforms give every student randomized numbers and limited submission attempts. Learn how to check your work step by step, practice similar problems, and copy clean LaTeX on Android.
Figure 01 · Verifying Randomized Portal Values & Exporting Clean LaTeX
Anyone taking high school or college math, physics, or chemistry today knows the stress of online homework portals like DeltaMath, WebAssign, ALEKS, or Mastering Physics / Chemistry:
- Every student gets randomized numbers: Looking up a textbook problem number on a forum shows a solution for v₀ = 15 m/s when your screen asks for v₀ = 22 m/s.
- Strict submission attempt limits: Miss a minus sign, a degree-to-radian conversion, or a significant figure on attempt 2 of 3, and your grade drops or your streak resets to zero.
- Formatting and LaTeX headaches: Entering complex fractions, radicals, matrices, or chemical equations into web input boxes is slow and error-prone.
Here is a practical, four-step workflow using Stemulus on Android to check your exact randomized numbers, catch algebra or unit slips before submitting, copy clean image-to-LaTeX math, and actually master the problem pattern before your quiz.
Step 1: Work the problem on paper and log your tentative answer first
The fastest way to tank your exam grade is using a solver to skip doing the work yourself, because online homework portals test the exact same problem types on proctored midterms.
Instead:
- Work the problem out on scratch paper using your randomized numbers.
- Open the Stemulus Homework Scanner App on your Android phone or tablet and snap a photo of the problem (or select a screenshot).
- Preview the crop to make sure only that single problem is framed (capturing an image never uses a scan credit until you confirm).
- Enter your own answer in the attempt field before tapping Check Problem.
Recording your own attempt keeps you honest: Stemulus saves your attempt right next to the worked solution so you can see whether you got it right on your own.
Step 2: Compare Step 01 and Step 02 to catch portal-specific traps
When an online homework portal marks your answer wrong, the mistake is almost always in one of three places. Use the numbered steps in Stemulus to audit your work before using your next submission attempt:
For DeltaMath & Calculus / Pre-Calculus portals
- Sign and factoring slips in limits and derivatives: Check Step 01 and Step 02 in our Word Problem & Calculus Solver to verify product rule, quotient rule, or chain rule signs, and confirm whether an inequality boundary flipped when dividing by a negative number.
- Exact vs. decimal form: Many portals require exact radical or fraction form (like (3√2)/4) rather than a rounded decimal. Inspect the symbolic step right before the final decimal evaluation.
- Geometry & Trigonometry: Use the Geometry Solver App to check whether a triangle law-of-cosines or radian/degree conversion caused the mismatch.
For WebAssign & Physics portals
- Unit conversions and vector components: In our Physics Solver App, compare Step 01 against your scratch paper to make sure centimeters were converted to meters, grams to kilograms, and incline angles used sin θ vs. cos θ correctly.
- Arithmetic substitution check: Supported calculations in Stemulus run an automated arithmetic check by substituting the final values back into the governing equation, catching squared-term and calculator entry errors.
For ALEKS & Chemistry portals
- Stoichiometric mole ratios and rounding: In our Chemistry Solver App, verify the coefficients of the balanced chemical equation in Step 01 and keep unrounded intermediate molar values until the final step so you don’t trigger a rounding penalty on the portal.
Step 3: Convert scanned equations from image to LaTeX in one tap
If you are writing up a physics or chemistry lab report, posting a question to your class discussion board (like Piazza or Ed Discussion), or organizing digital study notes in Notion or Obsidian, retyping equations by hand is tedious.
Every worked solution in Stemulus typesets mathematics cleanly and includes one-tap LaTeX copy. Scan a handwritten derivation or printed problem on Android, verify the steps, and copy the clean LaTeX string directly to your clipboard.
Step 4: Turn “Still stuck” portal problems into a 3-question Practice Round
Platforms like ALEKS and DeltaMath require you to solve multiple variations in a row to prove mastery. If you needed help on the first problem, don’t immediately gamble your next portal attempt:
- Save the scanned problem to a named Assignment in Stemulus and mark its status as Still stuck.
- Open the AI STEM Study Guide & Practice Generator for that assignment.
- Start a three-question Practice Round. Stemulus generates three fresh problems targeting the exact concepts you marked Still stuck.
- Use progressive hints (revealing Hint 1 first to check your setup, then finishing the math yourself). Remember: revealing the full worked answer in Stemulus lets you study the steps, but it never counts as getting the practice question right.
Once you can solve the practice round on your own, go back to your homework portal and knock out the remaining problems with confidence.

FAQ
Frequently asked questions
Why don't static answer keys work for DeltaMath, WebAssign, or ALEKS?
Platforms like DeltaMath, WebAssign, and ALEKS randomize the coefficients, angles, or given quantities for every student, and often regenerate a brand-new problem if you miss your submission attempts. You need a step-by-step solver that works with your exact numbers and teaches you the underlying method.
How can I check my answer before using my final submission attempt?
Work the problem on paper first, scan or type your exact problem into Stemulus on Android, and enter your tentative answer before tapping Check Problem. You can compare your setup step by step and catch sign, rounding, or unit errors before submitting online.
Can Stemulus convert a photo of an equation into LaTeX?
Yes. Every worked solution in Stemulus renders math in textbook notation and lets you copy equations and steps directly as clean LaTeX in one tap.
