618*2=1236
68*21=1428
You have 4 options for the first digit, 3 for the second, 2 for the third. Multiplying all this you get 4 x 3 x 2 = 24 options.
The only way to get an odd product when multiplying two whole numbers is when both of them are odd. Thus, in your example, the only way is by choosing the odd numbers 7 and 5, whose product is 35.
You can represent values using variables. This can only be done with whole numbers.
Estimating is not as helpful when multiplying very small numbers because the numbers aare very easy to answer
68*21=1428
Six does.
No. By adding 4+4+4 the answer comes to 12. To subtract the answer comes to 4. By multiplying it is 64.
Only when their GCF is 2.
It depends on the number of significant figures from two numbers you are multiplying. But when multiplying you use the same number of significant figures from the numbers you are multiplying with the LEAST number of significant figures. Example: 92,873.239 * 2 = 200,000 (because the number 2 has only 1 significant figure even tho 92,873.239 has 8 significant figures your answer still only has 1 significant figure)

No, multiplying a set of numbers can only come out as one product. Therefore, two numbers having the same prime factorization is impossible.
Yes. Natural numbers are counting numbers, equal to or greater than 0. The only ways a product can be less than its multiplicands is when multiplying fractions by fractions or multiplying a positive number by a negative number.
You only need two. 59 x 83 = 4897
Yes, but only if the rational number is non-zero.
In maths the product is the result of multiplying two numbers. You have only given one so there can be no product.
