there's no way to solve it
No.No.No.No.
A mole of any substance has the Avogadro's number of such units. As an example, a mole of hydrogen atoms is equivalent to 6.022 x 1023 atoms.
A simple law is the commutative addition law.
one example of a mathematical equation could be (+2x-5)-(-2x+5+10a) and the answer would be (-5a3+4x-2)
Yes, a mathematical expression can have no variables, but such an expression is usually not very useful. An example of a valid expression without variables is: 1+1=2
Like terms in mathematical problems are two variables that are the same. An example is 3x, x, 76x; because they all share x, they are like terms.
By definition, an equation has a solution. The word comes from "equal". Some mathematical problems do not have solutions. For example, 1/0 = X is a problem with no solution. You know, in this example that there is no solution because of the "divide by zero" rule. Most insoluble problems are insoluble because of some rule that keeps you from moving ahead.
No.No.No.No.
There are many mathematical tools. Arithmetical computation is one that is used daily.
The Lord's Prayer is one.
No. For example, division by 0 is not defined.

The LCM of 8 and 12 is 24.
A mole of any substance has the Avogadro's number of such units. As an example, a mole of hydrogen atoms is equivalent to 6.022 x 1023 atoms.
There are many limitations that mathematical models have as problem solving tools. There is always a margin of error for example.
The Mathematical pyramid dividend of 164 is 25 which goes into 164 six (6) times.
A simple law is the commutative addition law.
