(8 x 5) x 2
or
8 x (5 x 2)
They are: 8 times 17 = 136
It might be possible, but its much easier in the same units.
Knowing the multiplication properties can simplify the evaluation of 5 times 20 times 63 by allowing you to rearrange and group the numbers for easier calculation. For example, you can first calculate 5 times 20 to get 100, and then multiply that result by 63, making the final calculation straightforward. Alternatively, you can group 20 and 63 together as 1260, and then multiply by 5. This flexibility in grouping and rearranging can lead to quicker and more efficient calculations.
because it is easier than adding and subtracting so many times??
The result of multiplying two factors together is called the "product." In mathematical terms, if you multiply factors ( a ) and ( b ), the product is denoted as ( a \times b ) or simply ( ab ).
You need to factor it, into prime factors. Then, for every prime factor that appears an ODD number of times, you need to multiply 2306 by this prime factor. Multiply all such prime factors together to get your answer.
To find three numbers that multiply together to equal 40, we need to consider the prime factors of 40, which are 2, 2, 2, and 5. We can group these prime factors into three numbers: 2, 2, and 10. Therefore, the three numbers that multiply to 40 are 2, 2, and 10.

To multiply 6 times 198 mentally, you can use the expression (6 \times (200 - 2)). This simplifies to (6 \times 200 - 6 \times 2), which equals (1200 - 12 = 1188). This method makes the calculation easier by breaking it down into simpler components.
256 times 17 equals 4,352. To arrive at this result, you can multiply the two numbers directly or break it down into smaller parts for easier calculation.

To find two numbers that multiply to equal 166, you can use the factors of 166. The two numbers are 2 and 83, since (2 \times 83 = 166). Another pair of factors could be 1 and 166, as (1 \times 166 = 166).
