The sum of the number m and 7.1
(write it in a algebra expression? )

In mathematics when we use the numbers and letters to show the relationship between two quantities, the expression is called algebraic expression.

The sum of the M and 7.1 is M+7.1

We don’t know the value of M so we don’t know the exact value for sum of M and 7.1

When we writ this in algebraic expression,

 let S is the sum of M and 7.1

then the equation will be:

M  + 7.1 = N

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
