👉 Manually performing math involves using basic arithmetic operations—addition, subtraction, multiplication, and division—along with understanding number properties like commutativity (order doesn't matter for addition/subtraction) and associativity (order can be rearranged for multiplication/division)—to solve equations or calculate values without calculators. For instance, to solve 5 + 3 × 2, you first multiply 3 by 2 to get 6, then add 5 to 6, resulting in 11. Similarly, for 12 ÷ (4 + 3), you first add 4 and 3 to get 7, then divide 12 by 7, yielding approximately 1.71. This method relies on logical steps and understanding of number relationships rather than computational speed, making it a foundational skill for more complex mathematical concepts.
