To Calculate
する verb
When you calculate and determine (the calculation), you are determining the calculation. That's why this word is to calculate.
Unlike 計算する, which means “to calculate” in general, 算定する is a formal word that focuses more on the final value of a calculation, instead of the process of calculating itself.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
