Question Find the value of $-3 \times -4$ .

Studdy Solution

STEP 1

Assumptions
1. We are multiplying two negative integers.
2. The multiplication rule for two negative numbers states that the product is positive.

STEP 2

Apply the multiplication rule for two negative numbers.
$(-a) \times (-b) = ab$
Where $a$ and $b$ are positive numbers.

STEP 3

In the given problem, $a = 3$ and $b = 4$ . Substitute these values into the multiplication rule.
$(-3) \times (-4) = 3 \times 4$

STEP 4

Multiply the two positive numbers.
$3 \times 4 = 12$

STEP 5

Conclude that the product of $-3$ and $-4$ is $12$ .
$-3 \times -4 = 12$

STEP 1

Assumptions1. We are multiplying two negative integers.2. The multiplication rule for two negative numbers states that the product is positive.

STEP 2

Apply the multiplication rule for two negative numbers.(−a)×(−b)=ab(-a) \times (-b) = ab(−a)×(−b)=abWhere aaa and bbb are positive numbers.

STEP 3

In the given problem, a=3a = 3a=3 and b=4b = 4b=4. Substitute these values into the multiplication rule.(−3)×(−4)=3×4(-3) \times (-4) = 3 \times 4(−3)×(−4)=3×4

STEP 4

Multiply the two positive numbers.3×4=123 \times 4 = 123×4=12

STEP 5

Conclude that the product of −3-3−3 and −4-4−4 is 121212.−3×−4=12-3 \times -4 = 12−3×−4=12
