Remember (Find the topic, use the idea): Read the question and find its topic: hardware or software, units, memory, files, or editing text. Use that lesson’s idea — can you touch it, multiply to change units, RAM forgets, which file action, which shortcut. For unit sums, write the rule first (1 byte = 8 bits, 1 KB = 1024 bytes) and then multiply.
