  3. 47 + 36 = ? Answer: 83 Solution: Write the numbers vertically in your mind, aligning them by place value (ones and tens). 47 + 36 Add the digits in the ones column first: 7 + 6.
    Full step-by-step solution

    Let's add 47 and 36 step by step. Step 1: Write the numbers vertically in your mind, aligning them by place value (ones and tens). 47 + 36 Step 2: Add the digits in the ones column first: 7 + 6. 7 + 6 = 13 Step 3: Since 13 is a two-digit number, we separate it into 10 (1 ten) and 3 (3 ones). Write down the 3 in the ones place of the answer, and carry over the 1 (which is 1 ten) to the tens column. Step 4: Now add the digits in the tens column, including the carried-over 1. 4 (from 47) + 3 (from 36) + 1 (carried over) = 8 Step 5: Write the 8 in the tens place of the answer. Step 6: Combine the tens and ones digits: 8 tens and 3 ones makes 83. Final answer: 83
