Answer:
The algebraic expressions can be presents by words or equivalent expressions, so that its meaning remains same.
Step-by-step explanation:
Different ways to present algebraic expressions without changing their meaning:
1. We can describe the algebraic expressions in words so that its meaning remains same.
For example : 3x+y = Sum of 3 times of an unknown variables x and y.
2. We can describe the algebraic expressions in equivalent expressions, so that its meaning remains same.
For example : 6x+3y = 3(2x+y)
Therefore, the algebraic expressions can be presents by words or equivalent expressions, so that its meaning remains same.
