What's the analogy behind two positives = a positive?
Answer (2)
In mathematics, the principle that two positives make a positive means that when you add two positive numbers, the result is always a positive number. This concept can be illustrated through basic number addition, real-world examples like collecting items, and visualization on a number line. The underlying idea is that combining two quantities that are both above zero will always yield a greater positive quantity.

In mathematics, when we say that 'two positives equal a positive,' we are referring to the rules of multiplication and addition involving numbers.
Here's a simple breakdown:
Addition : When you add two positive numbers together, the result is always a positive number. For example, if you add 3 and 5, you get 8, which is also positive. Mathematically, 3 + 5 = 8 .
Multiplication : Similarly, when you multiply two positive numbers, the result is also positive. For example, multiplying 3 by 5 gives 15, which is positive. Mathematically, 3 × 5 = 15 .
Why does this happen?
In simple terms, positive numbers represent quantities that are greater than zero. When you combine positive amounts through addition or multiplication, you are essentially accumulating more of something, which naturally results in a positive outcome.
Summary:
When adding: Positive + Positive = Positive
When multiplying: Positive \times Positive = Positive
These basic rules help form the foundation of understanding more complex mathematical operations and number properties. It's important because it ensures consistency in how we work with numbers and solve problems.
