How many terms in each expression? 1)ab2+ab+a, 2)k-4, 3)m-n+2m?

Question

How many terms in each expression? 1)ab2+ab+a, 2)k-4, 3)m-n+2m?

Answer 1

each term is separated by the signs.

so :

1. ab2 & ab & a   three

2. k & 4   two

3. m & n & 2m  three

hope that helps!

Answer 2

Terms are separated by the operations of addition and subtraction.

Ex. 4 + x,  x^2 - 2x  ,  x + y + z,  w + z - h

The operations of multiplication and division do not separate terms.

Ex. 4x is considered one term

      2x^2 is considered one term

      (6x)/4 is considered one term

      (x^4 + x^2)/(x+1) is considered one term

So:

1) ab^2 + ab +a

This expression contains three terms since two addition signs separate the terms "ab^2", "ab", and "a".

2) k - 4

This expression contains two terms since a subtraction sign separates the terms "k" and "4".

3) m - n + 2m

This expression contains three terms since the operations of subtraction and addition separate the terms "m", "n", and "2m".

Answer 3

1)3 terms

2)2 terms

3)3 terms

according to my teacher, a term is separated with a positive or a negative sign...
