, x must equal -6. Ask students to check reasonableness of the solution. If there were negative six counters in the cup and we added positive two counters, would we end up with four negative counters? Together, model the equation . 5 + x = 8, and have students solve the equation.
Multiplying Negatives Makes A Positive
The fact that they both equal . 12. is not the point. 3 × 4. and . 4 × 3. actually . mean. different things but give the same result. (b) 3 × – 4 therefore means – 4 + – 4 + – 4 = – 12. So we could say that positive × negative = negative but I want people . to. remember WHY . and not just remember the RULE! (c) Students need to ...

It comes in two types, called positive and negative. Positive charge is the type of charge carried by protons. ... If lines 3 and 5 are nearly equal and around 10 V, your data is probably OK. Variations of ± 1 V are probably not significant. Analysis B4. What does the data in the table tell you about the distribution of charge on a hollow ...

“Adding positive and negative numbers” and “Subtracting positive and negative numbers” Manipulatives: counters to represent +1 and ─1. You could use poker chips in two colours, or squares of card in two colours, or squares marked + and ─ . Each team of students will need about 15 positive counters and 15 negative counters. Optional:

Use the charges to create an electric dipole with a horizontal axis by placing a positive and a negative charge (equal in magnitude but opposite in sign) 1 meter away from each other. (Axis of a dipole is a line passing through both charges.) Place positive charge on the left and negative on the right.

Sensitivity and specificity need not be equal. Developers of medical tests can manipulate the sensitivity and specificity--when one is increased, the other decreases. Create a probability table with columns D (disease) and W (well), and rows P (positive) and N (negative).

So the two locations where the potential is zero are 2.0 cm from the negative charge towards the positive charge, and 10.0 cm from the negative charge away from the positive charge. 31) [4 pts] An electron and a proton are apart.
