There are many different rules for multiplying, but in the end it is basically based off of memory. For larger numbers, it is different. You multiply one number at a time from right to left and add up each answer together to get the final answer.
72 You wold do 1x2=2 and then 1x7=7
x51
17
Then you would do 5x2=10 carry the 1 and then 5x7=35+1=36
72
x51
17
+360 The answer ends up as 377
Yes. Integers, Real Numbers, and even Complex Numbers can as well.
A general rule for multiplying fractions: You shall not multiply the denominator by the whole number,only the numerator.Another rule is you shall make the whole number as a fraction by putting the whole number as the numerator and 1 as the denominator before multiplying it.
In all of these cases the result is positive.
Yes, you can use the rule for multiplying by the reciprocal to divide whole numbers. To divide 10 by 2, you can rewrite the division as multiplying by the reciprocal of 2. This means you would calculate (10 \times \frac{1}{2}), which equals 5. Thus, dividing by 2 is the same as multiplying by its reciprocal.
If the two numbers have different signs, then the result will be negative. If the two numbers have the same signs, the result will be positive. This assumes all the numbers are non-zero.
Fractions and decimals are usually rational numbers. Besides, multiplying rational and irrational numbers is also similar.
Positive A simple rule to remember this is when multiplying two numbers with the same sign, the result is ALWAYS positive. When multiplying two numbers with different signs, the results is ALWAYS negative.
The result of multiplying numbers is called the product.
It is not as helpful when multiplying very small numbers because the numbers are going to be very east to answer. That is why estimating is not as helpful when multiplying very small numbers.
The rule for multiplying by 1 is, everything multiplied by 1 is the answer.For example, 2multiplied by 1 is 2.
no
It's a positive number. Here's the rule: In multiplication and division . . . -- If both numbers have the same sign, then the result of multiplying or dividing them is positive. -- If the two numbers have different signs, then the result of multiplying or dividing them is negative.
