The symbol i, We write, P.. positive -negative- numbersMath 6th Grade.In this lesson you will learn positive and negative numbers otherwise known as integers. An integer is a positive or negative whole number. Lets take a look, on this number line you can see that we have positive numbers and we have negative numbers. The positive numbers fall to the right of the zero, they increase as they move to the right. The negative numbers decrease as they go to the left of the zero, you can see that negative numbers are less then zero.www.mathexpress.tv
Multiplying & Dividing Positive & Negative NumbersVideos by Julie Harland yourmathgal.com Shows the rules for multiplying and dividing negative and positive numbers. Shows why negative times negative produces a negative number using counters.
Question : there is only one part of the rule i remember which is
negative + negative = positive
what is the rest?
Answer : positive and negative =negative positive and positive =positive negative and negative =positive
Answer : positive and negative =negative positive and positive =positive negative and negative =positive
Question : I have this homework that has negative and positive numbers in it and never learned it. I transferred schools in different states and we hadn't gotten to that lesson yet. If there is a rule, can you please tell me it and help me?! Please show your work if you can...
1. q - 14 = - 8
2. - 10 = z - 5
3. - 7 = y - 1
4. 3x = 39
5. - 7x = 42
6. 150 = - 15x
7. - 124 = - 2x
In exercises 8-10, write and algebraic equation for the sentence. Then solve the equation.

Answer : 1) q - 14 = - 8 Add to both sides of the equation 14: q - 14 + 14 = - 8 + 14 since -14 + 14 = 0, you can eliminate those 14s now: q = - 8 + 14 And subtract 8 from 14 to find: q = 6 I'll go faster in the next series: 2) - 10 = z - 5 Add 5 to both sides: - 10 + 5 = z so: - 5 = z or switch it: z = - 5 3. - 7 = y - 1 Add 1 to both sides: - 6 = y 4. 3x = 39 Divide both sides by 3: 3x/3 = 39/3 Since 3/3 = 1, you can eliminate those 3s, and get: x = 39/3 so: x = 13 5. - 7x = 42 Multiply both sides by-1 to get rid of the minus sign before the 7x: -7x(-1) = 42(-1) so: 7x = -42 Divide both sides by 7: x = -42/7 so: x = -6 6) 150 = - 15x Get rid of the minus sign before the 15x again: -150 = 15x Divide both sides by 15: -150/15 = x so: x = -10 7) - 124 = - 2x Get rid of minus signs (multiply both sides with -1): 124 = 2x Divide both sides by 2: 124/2 = x so: x = 62 8.
