a - b is simply a subtraction problem, such as 7 - 4, only when you wrote the equation you didn't know what the numbers would be. But you do know they are different quantities, so you use a and b to make it clear. Then later when you know what those quantities are, you put them in.

For example, you want to buy your friend a fruit basket, but they all contain Oranges and your friend doesn't like oranges. So you buy a giant fruit basket with 42 assorted fruits and take out the 4 oranges.

Let a = 42 (all the fruits in the basket) and let b = 4 (the number of oranges).

a - b = 42 - 4 = 38.

You are giving your friend 38 pieces of fruit.

In math and algebra, a product is the result of multiplication. The product of a x b is ab.

ma + mb = m(a + b) this is an algebra formule, what cyfers, NUMBERS STAND A and M for I suspect that slashes representing fractions are missing: m/a + m/b = mb + ma/ab = m(b + a)/ab

Do you mean F = abc + abc + ac + bc + abc' ? *x+x = x F = abc + ac + bc + abc' *Rearranging F = abc + abc' + ab + bc *Factoring out ab F = ab(c+c') + ab + bc *x+x' = 1 F = ab + ab + bc *x+x = x F = bc

The answer depends on whether ab represents a 2-digit number or, as in algebra, represents the product of a and b.If ab represents a 2 digit number, so that, in fact, it is equivalent to 10*a+b, then it is divisible by 2 if b = 0, 2, 4, 6 or 8 and divisible by 5 if b is 0 or 5. The value of a makes no difference.If ab represents the product of a and b and they are both integers, then ab is a multiple of 2 or 5 if at least one of a or b is a multiple or 2 or 5.It gets a lot more complicated in the latter case if they can be non-integers.The answer depends on whether ab represents a 2-digit number or, as in algebra, represents the product of a and b.If ab represents a 2 digit number, so that, in fact, it is equivalent to 10*a+b, then it is divisible by 2 if b = 0, 2, 4, 6 or 8 and divisible by 5 if b is 0 or 5.

juxtaposition - one may place two variables or expressions next to each other and imply an operator. e.g. a times b can be written ab.

idiosyncrasies of matrix are the differences between matrix algebra and scalar one. i'll give a few examples. 1- in algebra AB=BA which sometimes doesn't hold in calculation of matrix. 2- if AB=0, scalar algebra says, either A, B or both A and B are equal to zero. this also doesn't hold in matrix algebra sometimes. 3- CD=CE taking that c isn't equal to 0, then D and # must be equal in scalar algebra. Matrix again tend to deviate from this identity. its to be noted that these deviations from scalar algebra arise due to calculations involving singular matrices.

AND in Boolean algebra is represented by a dot, like multiplication. It can also be represented with parenthesis. "(A OR B) AND C" can be written as (A + B)C AND can also be represented with variables next to each other, just like in algebra: "A AND B" can be written as AB

For any two or more multiples in algebra. they are written as '2x' or 'ab' or '3ab' NB In algebra the multiplication sign 'x' is NEVER' shown. The '2x' means '2' multiplied to 'x' , or similarly 'ab' means 'a' multiplied to 'b'.
