Pa help po grade9 mathematics
I have learned that Studying mathematics not only will develop more engineers and scientists, but also produce more citizens who can learn and think creatively and critically, no matter their career fields. The workforce of tomorrow, in all fields, will demand it.
Mathematics makes our life orderly and prevents chaos. Certain qualities that are nurtured by mathematics are power of reasoning, creativity, abstract or spatial thinking, critical thinking, problem-solving ability and even effective communication skills.
I dont know whats the lesson but I hope this helps, at least for the introduction of your answer:)
