how do you subtract two vectors?
390800
To subtract two vectors, you put their feet (or tails, the non-pointy parts) together; then draw the resultant vector, which is the difference of the two vectors, from the head of the vector you're subtracting to the head of the vector you're subtracting it from.

Rule 3: Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. Basically, - (-4) becomes +4, and then you add the numbers. ... This would read “negative two minus negative 4”.

When you're subtracting exponents, the same conclusion applies: simply calculate the result if you can and then perform the subtraction as usual. If both the exponents and the bases match, you can add and subtract them like any other matching symbols in algebra. For example, xy + xy = 2_xy and 3_xy – 2_xy = _xy.

Subtraction of Algebraic Fractions. To subtract algebraic fractions, first express them in terms of their Lowest Common Denominator (LCD) and then subtract their numerators to obtain the numerator that is divided by the LCD to arrive at the answer.

Tips. Google spreadsheets can also subtract using the MINUS function. "=MINUS(A1,A2)" is equivalent to "=A1-A2."

If the dot product two vectors is 0, they are orthogonal; in other words, they are perpendicular. The dot product between two vectors →u,→v is given by →u⋅→v=|→u||→v|cos(θ), so →u⋅→v=0⟹cosθ=0⟹θ=π/2(90∘).

Just take the absolute value of their difference, then, if larger than 180, substract 360° and take the absolute value of the result. If the direction doesn't matter (you want the one that yields the smallest value), then do the reverse subtraction (mod 360) and calculate the smallest value of the two (e.g. with Math.

To perform a simple subtraction operation, you use the minus sign (-). To enter the formula in your worksheet, do the following: In a cell where you want the result to appear, type the equality sign (=). Type the first number followed by the minus sign followed by the second number.

To subtract binary numbers, simply align the 2 numbers and subtract as you would a regular problem. To subtract with the complement method, align the numbers and, if necessary, add zeros to the front of the second number to give it has an equal amount of digits.

You can isolate one variable in one equation, then substitute it in the second equation. Or you can manipulate one of the equations so that you have equal values of one variable, then subtract one equation from the other, eliminating the variable.
