Explanation
คิดเลข combines คิด, “to think or work out,” with เลข, “number.” It covers arithmetic, mental math, math exercises, and everyday calculations involving prices or shared costs. Common patterns include คิดเลขเก่ง “be good at arithmetic,” คิดเลขไม่เก่ง “be poor at arithmetic,” and คิดเลขเร็ว “calculate quickly.” คิดเลขในใจ means “do the calculation mentally.”
Usage
It is commonly used when doing school arithmetic, talking about someone's ability with numbers, or working out everyday amounts such as totals and each person's share of a bill. It is a natural conversational expression.
Caution
Do not use คิดเลข to ask a shop or restaurant for the bill; คิดเงินด้วย is a natural choice for that situation. For technical calculations or formal writing, คำนวณ may be more appropriate.
