You don't really times two numbers, you can however find the product of two numbers. Anyways, there are a number of tricks, but the easiest way is to break the number into easier pieces:
For example:
60 x 90 = (10 x 10) x (6 x 9) = 100 x 54 = 5400
We split the 10's out, because 10 x 10 is easy. And 6 x 9 is also easy.
60 x 12 = (6 x 10) x (4 x 3) = (2 x 3 x 10) x (2 x 2 x 3) = (2x2x2) x (3x3) x 10
=8 x 9 x 10 = 72 x 10 = 720
As you can see on this one, you had to keep breaking the numbers apart to find an easier combination, but ultimately it pans out. The problem is each time you break a number into more numbers, you are more prone to making a mistake trying to keep track of all the numbers.
Also, this method doesn't always work well, but it can still bemanageable:
11 x 12 = 11 x 4 x 3 = 44 x 3 or 33 x 4
You have to carry a digit now, and that's slightly harder to do. But you can still do it in your head. "4x3=12, carry the 1, 4x3=12+1 = 13, the answer is 132."
Sometimes though, it will be nearly impossible using this method:
33 x 77 = 3 x 11 x 7 x 11 = 21 x 112 = ???
Another method to make problems a little easier:
You can reduce a number by one factor:
33 x 7 = 11 x 3 x 7 = 10(21) + (21) = 210 + 21 = 231
If 3x7=21 is the factor, I basically extracted one factor to make the problem 10(21) and then just added that extracted factor back in. This takes a little longer to grasp than the above method.

What do you get with three numbers?
It depends on what three numbers it is. For example: 2 times 2 times 2 actually equals 8 if you know your exponents.
What 4 numbers make 64?
There are many combinations of four numbers that can multiply to make 64. One example is 2, 2, 2, and 8, since (2 \times 2 \times 2 \times 8 = 64). Another combination is 4, 4, 2, and 2, as (4 \times 4 \times 2 \times 2 = 64). Various other sets of numbers can also yield the same product.
What numbers go into 144?
144 is 2 times 2 times 2 times 2 times 3 times 3.
How to times a negative number?
When you times 2 positive numbers together, you get a positive answer. When you times 2 negative numbers together, you get a positive answer. When you times a positive number and a negative number, you get a negative answer. (e.g. -2 x 4 is the same as -2 + -2 + -2 + -2, which is the same as -2 - 2 - 2 - 2 = -8)
What is 160 as the product of its prime numbers?
The number 160 can be expressed as the product of its prime factors by first dividing it by the smallest prime numbers. The prime factorization of 160 is (2^5 \times 5^1). Thus, 160 can be written as (2 \times 2 \times 2 \times 2 \times 2 \times 5).
What does 49 times 2?
49 times 2 does nothing! It is a number and numbers don't DO anything!
What two numbers equal 34?
the numbers are 17 times 2.
Can you predict the numbers of times that you can get head or tail when you flip a coin 5-times and why it is happen?
you cannot predict how many times you get heads or tails but however you can predict the probability it will hit heads or tails only which is don by multiplying 1/2 by itself 5 times
What three numbers equal 1024?
The three numbers that can equal 1024 can be 2, 2, and 256, since (2 \times 2 \times 256 = 1024). Alternatively, another set could be 4, 4, and 64, as (4 \times 4 \times 64 = 1024). There are multiple combinations of numbers that can yield the same product.
What prime numbers can you multiply to get 200?
three times 2 and two times 5 that is 2*2*2*5*5
What 3 numbers can you multiply to get 64?
You can multiply the numbers 4, 4, and 4 to get 64, since (4 \times 4 \times 4 = 64). Alternatively, you could use the numbers 2, 4, and 8, as (2 \times 4 \times 8 = 64) as well.
What are the numbers if the number added to 8 times the numbers reciprocal is 6?
2 and 4
