A constant is a number which is fixed in an question. On the other hand, a variable is a number which can change.
In your expression, 6 + axb, you have 1 constant (6), and 3 variables (a,x, and b).
Hope this helps :)
f(x)= axb or y= axb
axb + cxd
V=h/3 (axa + axb + bxb)
it denotes the set of ordered pairs with elements of A and b in the format (a,b)
cfm=.32X(aXb)Xface velocity/144 a= width b=length
f(x)= axb or y= axb
AxB=BxA (AxB)xC=Ax(BxC) Ax(B+C)=AxB+AxC Ax1=A Ax0=0
(axb)x(cxd)
If A and B are vectors then AxB=ABsin(AB). If A and B are not zero then AxB is zero if and only if sin(AB)=0 meaning the angle between A and B is a multiple of 180 degrees, in other words parallel.
A+B=B+A BxA=AxB
if x = multiplication. its as written, which would be abc ex. 3x4x5 = (3)(4)(5) = 60 if x= cross production, then you cross axb first, then bross (axb) x c where (axb) is wut u got by crossing axb. This is if u have no brackets. its just axbxc
The Commutative law states that, if AxB=y, and BxA=y, then AxB=BxA Or we can just say it says AB=BA where A and B are any numbers, real or complex.
Supplementary angles.
The airport code for Maxson Airfield is AXB.

NAND gates are universal gates and can be used to construct any of the logic gates (AND, OR, NOT, NOR, XOR, XNOR). The easiest way to figure this out is to use basic Boolean Laws. For instance, to create a NOT gate (A'), tie one of the NAND gate's input to logic high: (A+1)' = A'. To create an AND gate (AxB), use two NANDs in series, with the second one configured as an inverter: (AxB) = ((AxB)')'
