Math Mixed Addition and Subtraction Worksheets

1. Customizable Difficulty Levels

You can generate arithmetic problems with different number ranges to suit various learning stages:

Each option includes combinations of problems with different digit lengths. For example, within 20 you can generate combinations like: 1-digit + 1-digit - 1-digit, 1-digit + 1-digit + 1-digit, 2-digit + 2-digit - 2-digit, or 2-digit - 1-digit + 1-digit. You can also customize the number of terms in each problem to match different difficulty levels.

2. Add Brackets to Change the Order of Operations

You can include parentheses (), square brackets [], or curly braces {} in the problems to change the order of operations and increase the challenge.

3. Supports Multiple Printable Paper Types

The generated worksheets are neatly formatted and support both A4 and Letter paper sizes—perfect for use in classrooms or as homework.

4. Randomized Arithmetic Problems

Each worksheet is generated randomly. You can also choose whether to allow repeated problems or ensure all problems are unique.

1. Choose Problem Type

Problem types include filling in missing numbers in the equation or finding the missing answer.

2. Choose Answer Range

The generator supports various answer ranges for addition and subtraction problems:

Select the appropriate range based on the student’s learning level. Each range includes flexible structures—for example, “within 10” problems may include formats like 3-number mixed addition/subtraction, 4-number problems, or even 5-number problems using only single-digit numbers.

3. Choose Allowed Operations

You can choose between all-addition, all-subtraction, or a mix of both operators.

For example, choosing “Mixed Addition and Subtraction” will generate problems that include both “+” and “−”. Choosing “Addition Only” or “Subtraction Only” will generate problems with only those respective operators.

4. Choose Problem Structure

Problem structure refers to how many numbers are involved in each mixed operation question. For instance, a “within 20” problem may include a structure of 3, 4, or 5 numbers in one equation.

5. Choose Allowed Brackets

Adding brackets helps introduce the concept of operation order and increases difficulty. The generator supports the following bracket types: “()”, “[]”, and “{}”.

Examples: (9 + 3) - 1 = ______, (2 + 17) - 12 = ______, 8 + (13 + 15 - 12) - 12 = ______, [(13 + 9) - 19] + 5 - 1 = ______.

6. Allow Duplicates

Choose whether duplicate problems are allowed in your printable math worksheet. Choosing "No Duplicates" ensures all generated problems are unique.

7. Choose Number of Pages

Choose how many pages of worksheets you want to generate. Each page includes a fixed number of problems and is automatically laid out in a clean, print-friendly format. This option lets you control the total number of practice questions.

8. Choose Paper Type

Choose the Paper type compatible with your printer. We support A4 (210 × 297 mm) and US Letter (8.5 × 11 inches), the two most commonly used paper sizes in homes and schools around the world. This ensures your worksheets are ready to print and use without formatting issues.
