Question

How do you find the product $ - 3 \cdot 4$ ?

Answer 1

Hint: We are multiplying numbers, just remember two things. First, two negative numbers will always give a positive number. Second, if you multiply only one negative value with the positive value , your answer will also be negative always . Just remember these two rules and the rest is simple multiplication only.

Complete step-by-step solution:
We have given $ - 3 \cdot 4$ , We know that , if we multiple only one negative value with the positive value , our answer will also be negative always , Therefore, we will get ,
$ - 12$ We get the required result.

Note: Just remember two things. First, two negative numbers will always give a positive number. Second, if you multiply only one negative value with the positive value , your answer will also be negative always . Just remember these two rules and the rest is simple multiplication only. In order to avoid confusion and to make sure that everybody always arrives at the identical result, mathematicians established a typical order of operations for calculations that involve over one mathematical operation. Arithmetic operations should be dole out within the following order:
1. You must Simplify the given expressions inside parentheses ( ), brackets [ ], braces and fractions bars first.
2. Then you have to evaluate all the powers present in the given expression.
3. Then you have to do all multiplications part first and then the divisions part from left to right direction.
4. Then you have to do all additions and then the subtractions part from left to right direction.
