Answer:
sum
Step-by-step explanation:
An algebraic expression is basically a combination of variables, constants and arithmetic operations : [tex]+,-,\times ,\div[/tex]
Constant is a quantity whose value remains fixed and whose value does not change . Constants are denoted by letters a , b , c ...
Variable is a quantity whose value may vary and does not remains constant.Variables are denoted by letters x , y, z, u ,v ...
Arithmetic operations are used to combine variables and constants .
For example : [tex]2x+y+x+z+4x=7x+y+z[/tex]
Here, the result we obtained i.e 7x+y+z is called a sum .
The result after adding a set of numbers or algebraic expressions is called a sum
