Into the Negative Zone: Demystifying Negative Numbers

Welcome to the Clara James Podcast, where we delve into Maths, English, and tutoring. Today's focus is on negative numbers, a topic that stumps many students.

Let’s use an analogy involving earth mounds and holes to understand negative numbers better. For instance, if you have 5 meters of earth and remove 3 meters, you're left with 2 meters – simple subtraction. But when subtracting a larger number from a smaller one like 3 minus 5, imagine digging below ground level; this result is -2 because you've gone two meters past zero.

Adding negatives can be visualised similarly: starting in a hole (negative value) and filling it back up (adding positives). If we start at -3 meters deep and add 5 meters of soil, we end up with a mound that's now 2 meters high above ground level.

When dealing with both addition and subtraction of negatives like in "2 minus (-5)", remember two negatives make a positive – so it becomes "2 plus 5", equalling +7.

Multiplication with negatives follows its own rule: multiple groups of negative values result in more extensive negative totals (e.g., "-3 times five" equals "-15"). However, multiplying two negatives together turns them into positives ("minus three times minus five" gives us "+15").

Finally, division maintains the logic seen in multiplication; dividing by or through negative amounts affects the sign accordingly ("-15 divided by +3" yields "-5").
