Basic Arithmetic Symbols

Basic Arithmetic Symbols problems use custom symbols (like ⊕, ⊗, ◊) to represent standard arithmetic operations (+, -, ×, ÷). You must substitute the actual operations and evaluate the expression following proper order of operations (BODMAS/PEMDAS).

Introduction to Basic Arithmetic Symbols

Basic Arithmetic Symbols problems use custom symbols (like ⊕, ⊗, ◊) to represent standard arithmetic operations (+, -, ×, ÷). You must substitute the actual operations and evaluate the expression following proper order of operations (BODMAS/PEMDAS).

Prerequisites

Basic arithmetic operations (+, -, ×, ÷) Order of operations (BODMAS/PEMDAS) Understanding of symbol substitution Basic calculation skills
Why This Matters: Basic Arithmetic Symbols problems are fundamental to symbol notation sections. You can expect 2-3 questions in SSC CGL, 2-3 in Banking PO, and 2-3 in Railways RRB exams.

How to Solve Basic Arithmetic Symbols Problems

1

Step 1: Note the mapping of each custom symbol to its arithmetic operation

2

Step 2: Replace each custom symbol with the corresponding arithmetic operator

3

Step 3: Apply order of operations (multiplication/division before addition/subtraction)

4

Step 4: Evaluate from left to right for operations of same precedence

5

Step 5: Calculate step by step to avoid errors

6

Step 6: Double-check your substitution and calculations

Pro Strategy: Always substitute symbols first, then apply standard order of operations. Write the substituted expression clearly before evaluating.

Example Problem

Example: If ⊕ = +, ⊗ = ×, and ◊ = -, then evaluate: 5 ⊕ 3 ⊗ 2 ◊ 1 Solution: Step 1: Substitution: ⊕ → +, ⊗ → ×, ◊ → - Step 2: Expression becomes: 5 + 3 × 2 - 1 Step 3: Order of operations: Multiplication first: 3 × 2 = 6 Step 4: Expression: 5 + 6 - 1 Step 5: Left to right: 5 + 6 = 11, 11 - 1 = 10 Answer: 10

Pro Tips & Tricks

  • Create a quick reference table of symbol → operation mappings
  • Remember: Multiplication and division have higher precedence than addition and subtraction
  • When operations have same precedence, evaluate left to right
  • Use parentheses mentally to group operations with higher precedence
  • Check if the expression contains division - ensure no division by zero
  • For long expressions, evaluate step by step and write intermediate results

Shortcut Methods to Solve Faster

First substitute, then evaluate using BODMAS
Multiplication/division before addition/subtraction
Same precedence = left to right
If only addition/subtraction, evaluate in any order

Common Mistakes to Avoid

Forgetting to substitute all symbols
Ignoring order of operations (evaluating left to right without precedence)
Misplacing the mapping (confusing which symbol means which operation)
Not handling division carefully (integer vs decimal results)
