Question

Write the phrase "the sum of the number and 23 less than that number" as a mathematical expression​

Answer 1

N-(23+n) less than is subtraction and sum is addition

Answer 2

x + ( x - 23 )

Step-by-step explanation: Sum means addition (something + something = SUM) . The word "and" means its a separate problem so the parenthesis are used to create x - 23 because "less than" means subtraction.
