calculation techniques

Calculation techniques are methods used to solve mathematical problems efficiently and accurately. They include mental math (doing calculations in your head), written methods (like long division or multiplication), and using tools such as calculators or computers. Techniques often involve breaking complex problems into simpler steps, recognizing patterns, or applying formulas. For example, estimating an answer helps check if a detailed calculation makes sense. The goal is to choose the most effective approach for the problem at hand, whether quick mental estimates or detailed, step-by-step solutions, to arrive at correct and reliable results.
