Unlike terms can't be add together as for example 2x and 3y
The terms of a sequence added together is the sum.
a+a+a+a+b+b - add the like terms =4a+2b 4a and 2b cannot be added because they are not like terms.
2a+3b+4c cannot be added. They are not like terms. Like terms need to have the same variable in order to be added.
Only like terms can be added or subtracted. 10m and 1s cannot be added; but divided, 10 m/s becomes a velocity.
Unlike terms are terms in an equation that are different. These terms cannot be combined. Like terms, however, can be combined.
You can add and subtract coefficients when they occur in like terms, which means they have the same variable. 2x + 3x = 5x (This addition can take place because all of the variables are x, and are therefore like terms.) and 5y - 2y = 3y (This subtraction can take place because all of the variables are y, and are therefore like terms.) However, if the variables differ, they are unlike terms, and you cannot add or subtract the coefficients. For example: 2a + 3b cannot be added because a and b are different variables, and therefore unlike terms. 3c - 2d cannot occur because c and d are different variables, and therefore unlike terms..
We cannot see the salt particle when it is added to the water because it dissolves
Australia cannot be described as small.
Terms of an Expression
2x+x+x+9x+2+12 - add the like terms =13x+14 13x and 14 cannot be added because they aren't like terms.
Plane, line and point. These are terms that are universally called the terms that cannot be defined.
1/37 cannot be expressed in lower terms.
