# What is negative 3 multiply by 5?

012

Whenever you multiply a negative number by a positive number, you get a negative number. If you multiply two negative numbers together, you get a positive number.

Therefore...

3 x 5 = 15

-3 x 5 = -15

-3 x -5 = 15

## Related Questions 3 x -5 = -15 since negative (-) number multiply with positive (+) number is negative and negative multiply with negative gives positive result/answer. Whenever you multiply with negative digit(s) with a positive digit(s) the answer alway goes negative. 5 * -3= -15 Yes. When you multiply two negative numbers, the answer is positive. To multiply a negative and positive just multiply regularly and then make negative ex. 6*-5=-30 In general, here are the rules for multiplying signed numbers: positive x positive = a positive 4 x 5 = +20 positive x negative = a negative 4 x -5 = -20 negative x positive = a negative -5 x 4 = -20 negative x negative = a positive -5 x -4 = +20 When multiplying two negative numbers you multiply as you would with regular positive numbers the product will ALWAYS be positive. Example: -3 x -3 = 9 when you multiply 2 of them it's positive, 3 and it stays negative.  =when you multiply negative integers the answer is going to be negative because n-multiply by n- equals n+ but when yu multiply n+ by n- it equals n- so you basicly multiply the numbers and the answer would be ah negative.==when you multiply negative integers the answer is going to be negative because n-multiply by n- equals n+ but when yu multiply n+ by n- it equals n- so you basicly multiply the numbers and the answer would be ah negative.= There are no two real numbers that do, but the complex numbers (2 + i) and (2 - i) will.If you want two numbers that multiply to negative 5 and add to positive 4 then: -1 and 5If you want two numbers that multiply to negative 5 and add to negative 4 then: 1 and -5  To multiply two integers with different signs, multiply them together as though both were positive and then make the result negative.Examples:-2 x 5 &rarr; 2 x 5 = 10, made negative &rarr; -10&rArr; -2 x 5 = -103 x -4 &rarr; 3 x 4 = 12, made negative &rarr; -12&rArr; 3 x -4 = -12To multiply two integers of the same sign together, ignore the sings and just multiply them as positive numbers.-2 x -5 &rarr; 2 x 5 = 10 &rArr; -2 x -5 = 103 x 4 = 12These rules apply to all numbers, not just integers. The sign of a product of three negative integers is a negative sign.Example:-3*-3*-3=-27 If you have a list of numbers, some positive some negative, and want to multiply them together, first just multiply them without regard to the sign. Then if the number of negatives is odd put a negative sign in front of the answer while if it is even don't do anything. So, for example, (-3)*(-4)*(2)*(-5) then 3*4*2*5 = 120 there are three negative numbers (odd) so the answer is -120 or (3)*(-4)*(2)*(-5) again 3*4*2*5 = 120 there are two negative numbers (even) so do nothing: the answer is 120  The answer to this depends on what you are doing with the numbers..... * A negative added to a negative gives a negative (-3) + (-5) = -8 * A negative subtracted from a negative may give either a negative or a positive (-3) - (-5) = +2 (-5) - (-3) = -2 * A negative multiplied by a negative gives a positive (-3) x (-5) = +15 * A negative divided by a negative gives a positive (-3) &divide; (-5) = +0.6  3 negative 5 and 3 equals negative 2 easy question (-5) + 3 = (-2) Move the decimal point left to multiply by a negative power of ten. For example, 5X10-3 is 0.005  No, as that 3 is positive, and negative 5 is not.  Any two numbers that multiply to 30, one having a negative sign before it. So, the list of possible integers: -1, 30 (negative 1, 30) -2, 15 (negative 2, 15) -3, 10 (negative 3, 10) -5, 6 (negative 5, 6) 1, -30 (1, negative 30) 2, -15 (2, negative 15) 3, -10 (3, negative 10) 5, -6 (5, negative 6) If both of the numbers were negative, however, this would produce a positive answer. If the two numbers are the same (ex: -5 x -3) then the answer will be positive. SO the answer would be +15 If they are different (ex: +3 x -2) then the answer will be negative. SO the answer would be -6 Integers: 5 and -3 3 and -5 15 and -1 1 and -15 There are MANY other #s that can be multiplied to get -15, but those have fractions (i.e. 30 and -0.5) RULE TO MULTIPLY TO A NEGATIVE NUMBER: POSITIVE# x NEGATIVE# = NEGATIVE# ###### Math and ArithmeticSchool SubjectsNumbers AlgebraPotatoes Copyright © 2020 Multiply Media, LLC.
