What does - and - make in algebra ? does it make - or + ?

Answer 1

it depends on whether you are adding, subtracting, multiplying or dividing the numbers in question. Generally, the following applies:

ADDING
If you add two negative integers, the result is negative
MULTIPLYING
If you multiply two negative integers, the result is positive
DIVIDING
If you divide two negative integers, the result is positive
SUBTRACTING
If you subtract two negative integers, you keep the sign of the greater integer.

Answer 2

Two signs the same make a plus. So the answer is a plus. I passed Maths in College by 90%. Top of class by a full 9%.

Answer 3

- plus - equals - For example, -3 + (- 5) equals -8

- minus - depends on the numbers involved e.g. -5 - (-2) = -5 + 2 = - 3 or -2 - (-5) = -2+5 = 3

- multiplied by - = + e.g. -3 multiplied by -5 gives +15

- divided by - gives + e.g. -25 divided by -5 gives +5

Answer 4

Example; -3 + -3 = -6 because they have boths signs.

Addition
If they have like signs, follow theeir signs
If they have unlike signs, subtract the numbers and copy the sign of the bigger number.

Multiplication
If they have like signs, the sign is positive and if they have unlike signs, the sign is negative.

Answer 5

A negative times a negative equals a positive. (-2x*-3x=-6x)

A negative minus a negative requires you to change the subtraction sign to an addition sign and the second negative number to a positive. (-6x--3x=-6x+3x=-3x)

Answer 6

Adding two negative numbers together will give you a negative number. However, multiplying two negative numbers will give you a positive number.

Answer 7
