14... yay I'm so clever!!!

Let the number be x and if you mean 7*(x+5) = 133 then the value of x worls out as 14

Just work the problem backwards. The answer is 248. Something was divided by 12 in order to get it. If we MULTIPLY 248 by 12, we will find that number. We get 2,976. Now, we need to ADD 14, since 14 had originally been subtracted from the number we're looking for. Adding 14 we get 2,990.

Suppose we have 6 x 3, that is a "multiply" operation. What it means is that if you start with zero and add to it 6 once, then to the result add another six, then to the result add another six, what would be the result. The result would be 0+6 = 6 6+6 = 12 12+6 = 18 "Multiply" means starting with zero, successive addition of a number a certain number of times retaining the accumulated value through the operations. It is cumbersome to do it this way and so we resort to "Multiply"

There is no such number. You can start with a different number and end with different ones.

When you square a number, you multiply it by itself and the result is the square of that number.When you take the square root of a number, you start with an number and figure out what smaller number would produce your starting number if it were to be multiplied by itself.

You start with 1 0r 0. one of them,......................I think............

The expression is: 5(b + x)

It depends. If you start with a positive number, then multiply by a positive greater than one and the answer is greater; multiply by 1 and the answer is the same; multiply by a number between 0 and 1 and the answer is smaller; multiply by 0 and the answer is 0; multiply by a number less than 0 and the answer is negative.

arrange and multiply the number like whole numbers. count the number of decimal places. start from the rightmost, put the decimal point based on the total number of decimal places

Start with any number - say x. Pick any other number which is not 0, say y. Then, if you multiply x by y and then divide the result by y you will be back to x. Thus, "multiply by y" followed by "divide by y" is equivalent to do nothing. The first undoes the second. Also, it works in reverse in the sense that you can divide by y first and multiply by y afterwards.

For a start, if you want cubic yards, then all your measurements need to be calculated in yards. Measure the radius of the cylinder.... half the distance from one side, through the centre, to the other side - this measurement is usually refered to as r. Next, measure the height of the cylinder - this is usually called h. Now, multiply r by itself, and multiply the result by h. Now you need to multiply that result by pi - the relationship between a circle and its radius. This is usually given as 3.1416 Now you've got cubic yards. If your measurements are taken in feet, then you need to divide the result by 27, which is the number of cubic feet in a cubic yard.

That depends on the start number. Whatever number you're starting with, multiply it by 1, 2, 3, 4 and 5.

5,5,1,25, just start from the smallest number and multiply then keep going up the numbers.

Start by taking the number in Celsius and multiply it by 9. Then divide that number by 5, and then add 32. This is how you convert Celsius to Fahrenheit or use the equation F = (9/5)C + 32In this case, the answer is: 35.3ºC = 95.54ºF

It is well known that if you multiply a positive number (it doesn't have to be an integer) by another positive number the result is always a positive number. For example (+2.3) x (+2) = +4.6 Similarly, at school you learn that if you multiply a positive number by a negative number the result is always a negative number. For example (+19) x (-2) = -38 When you multiply two negative numbers you must get a positive result because of the way negative numbers "work", but why that is so is not usually explained at junior or high school. You learn why as part of learning about complex numbers in higher math at technical college or university. To be very brief, it is all to do with the behaviour of the operator "i". (For more information about it please see the answer to the related question shown below.) Because i2 is defined to be equal to -1 then it follows that i2 x i2 = +1 for the following reason: multiplying something by i2 means "apply the operator i twice" so, if you start with a positive number, multiplying it by i2 makes that positive number into a negative number. If you multiply that negative number by i2 again you make the result into a positive number. Overall you are applying the operator i four times so you can say that i2 x i2 (which is the same as i4) means "apply the operator i four times" and doing that gives a result which is a positive number. For example (-1) x (-2) = +2 could be written as: [(+1) x i2] x [(+2) x i2] = +2 x [(i2 x i2)] = +2 or even as (+1) x i2 x (+2) x i2 = +2 x i4 = +2

You don't know where to start until you remember that 16% is the same as 0.16 . Then you just multiply the number by 0.16, and that product is 16% of the number.

Start by taking the number in Celsius and multiply it by 9. Then divide that number by 5, and then add 32. This is how you convert Celsius to Fahrenheit or use the equation F = (9/5)C + 32In this case, the answer is about 46.4 degrees Fahrenheit.

Start by taking the number in Celsius and multiply it by 9. Then divide that number by 5, and then add 32. This is how you convert Celsius to Fahrenheit or use the equation F = (9/5)C + 32In this case, the answer is about 14 degrees Fahrenheit.

Start by taking the number in Fahrenheit and subtracting 32. Then divide the number by 9, and then multiply it by 5. This is how you convert Fahrenheit to Celsius or use the equation C = (F - 32) × 5/9In this case, the answer is about 26.67 degrees Celsius.
