Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Addition
Addition is one of the basic arithmetic operations. It is used to calculate the total or sum of two or more numbers. When we add numbers, we join them together to find out how much they add up to. For example, if you have 3 apples and get 2 more apples, addition helps us find the total number of apples: 3 + 2 = 5.

In our exercise, we add 45 and 7. We write this as: 45 + 7. The '+' symbol stands for addition. When we perform the addition, we end up with 52. So, 45 added to 7 equals 52.
Identifying Key Numbers
Identifying key numbers in a mathematical problem is crucial. It helps us understand what numbers we are working with and how to manipulate them.

Here are some tips to identify key numbers in a phrase:
  • First, read the entire phrase carefully.
  • Look for any numerical values mentioned.
  • Take note of these values as they are essential for forming the mathematical statement.
In our exercise, the phrase mentions the numbers 45 and 7. These are our key numbers and we will use them to formulate our mathematical statement.
Formulating Mathematical Statements
Formulating mathematical statements involves translating words into mathematical expressions or equations. This step helps us solve word problems by converting them into a more straightforward mathematical form.

To formulate a mathematical statement:
  • Identify key numbers and the operation required.
  • Translate words like 'added to' into mathematical symbols. In this case, 'added to' translates to '+'.
  • Write the numbers and the operation in a mathematical form.
For the given exercise, the phrase '45 added to 7' translates into the statement '45 + 7'. Then, we perform the addition to simplify the expression: 45 + 7 = 52.
