The line in a fraction can be read as "divided by." -4 divided by 15 is the same as -4/15
Yes it can. It is -4/15.The reason that it can is that the set of real numbers is a field.
4:8=8
A plus number.
Anything divided by itself equals one.
following multiplication integer rules and division rules, you should get: "MULTIPLICATION: minus times minus is plus (negative x negative = positive).....minus times plus is minus (negative x positive = negative).....plus times plus is plus (positive x positive = positive) DIVISION: minus divi minus is plus (negative ÷ negative = positive)......minus divi plus is minus (negative ÷ positive = negative).....plus divi plus is plus (positive ÷ positive = positive)" a division problem is a multiplication problem in disguise
x^2 - y^2 - 4 is in its simplest form.
(4x - 3)(16x^2 + 12x + 9)
The question contains an expression but not an equation. You cannot solve an expression.
It is undefined. Division by zero is not defined: it is not an operation that has any meaning. Consequently, an expression containing "divided by zero" is not valid.
x does not equal -1, because if x is minus 1, x plus 1 is zero and division by zero is not defined.
8-5+43 divided by 8
(35 - 16)/4 = 19/4
No, it is not. To be correct, the expression requires parenthesis, which are missing.
4
Division before subtraction.
That expression represents average speed during the time.
19
A mathematical expression that forms part of a fraction or proportion, is part of a series, or is associated with another by a plus or minus sign.
Work the problem the same as usual, but then prefix the answer with the appropriate sign. First perform the division--numerator divided by the denominator--without regard to the sign. The sign of your answer depends on the combination of the signs of the numerator, the denominator, and the fraction itself. * If there are an even number of minus signs, the answer is positive. * If there are an odd number of minus signs, the answer is negative. * If there are an no minus signs, the answer is positive.
