Verdict
The clearest difference is ads: Photomath at none against Calculate84's shown. Photomath also leads on ratings volume (733K vs 54K) and iOS requirement (14.0 vs 18.0). Calculate84's advantage is review sentiment (75% vs 61%) and update cadence (fortnightly vs monthly). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Photomath sells 9 in-app purchases, starting at $5.99 per month and Calculate84 sells 6 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.8 for Photomath against 4.8 for Calculate84.
