multiplying. adding is permeter. sorry bout my spelling. not the best at it
2. multiplying 2 and 2 is the same as adding 2 and 2.
Adding and subtracting fractions can ONLY be done if the denominators are the same; then the calculation is done by adding or subtracting the numerators. Multiplying (and dividing) fractions does not require the denominators to be the same. To divide by a fraction the divisor is inverted (the original numerator becomes the new denominator and the original denominator becomes the new numerator) and then the fractions are multiplied. Multiplying fractions is achieved by multiplying the numerators together AND multiplying the denominators together. A whole number is the same as a fraction with the whole number as the numerator and a denominator of 1, so when multiplying by a whole number the denominator is multiplied by 1 (leaving it the same) and the is multiplication is effectively just multiplying the numerator by the whole number.
No, that's perimeter. Area is multiplying the length times the width.
The perimeter is found by adding the length of each side. The area is found by multiplying the length of the square by the width.
The surface area of a prism is calculated by adding the area of the walls to the area of the top and bottom. The area of the walls is calculated by multiplying the perimeter of the top by the height of the wall.
Adding the logs of numbers is equivalent to multiplying the numbers. People think adding is easier than multiplying.
You have to line up the decimal when adding but not when multiplying. Example: This one is adding 23.56+89.45 23.56 89.45 This one is multiplying 23.54*4.506 23.54 4.506
By taking the width and length of each room to calculate the floor area by multiplying them together and adding all the room floor areas together
They aren't. The rules are the same as those for adding/subtracting or multiplying integers. Just be careful of the decimal point's location.
when you are only adding or multiplying.
