Mental Math Strategies

Mental math strategies are techniques to perform calculations in your head quickly and accurately, without paper or calculator. They involve methods like breaking numbers into parts (decomposition), rounding to simplify, using known facts (like times tables), and adjusting results for accuracy. For example, to add 48 and 27, you might think of 50 + 25 = 75, then subtract 2 to get 73. These strategies improve speed and confidence, making everyday math tasks easier and fostering better number sense without relying on tools.
