Divide Section (Whole Number + Remainder)

2 Digit Numbers

Step1: Calculate 24÷12

$24 \div 12 = 2$ (remainder 0)

Step2: Calculate 75÷15

$75 \div 15 = 5$ (remainder 0)

Step3: Calculate 30÷14

$30 = 14 \times 2 + 2$, so $30 \div 14 = 2$ remainder $2$

Step4: Calculate 88÷9

$88 = 9 \times 9 + 7$, so $88 \div 9 = 9$ remainder $7$

3 Digit Numbers

Step1: Calculate 420÷105

$420 \div 105 = 4$ (remainder 0)

Step2: Calculate 342÷114

$342 \div 114 = 3$ (remainder 0)

Step3: Calculate 625÷230

$625 = 230 \times 2 + 165$, so $625 \div 230 = 2$ remainder $165$

Step4: Calculate 958÷301

$958 = 301 \times 3 + 55$, so $958 \div 301 = 3$ remainder $55$

4 Digit Numbers

Step1: Calculate 1580÷79

$1580 \div 79 = 20$ (remainder 0)

Step2: Calculate 6325÷253

$6325 \div 253 = 25$ (remainder 0)

Step3: Calculate 4001÷46

$4001 = 46 \times 86 + 45$, so $4001 \div 46 = 86$ remainder $45$

Step4: Calculate 8234÷413

$8234 = 413 \times 19 + 297$, so $8234 \div 413 = 19$ remainder $297$

Order of Operations

Step1: Solve $3 \times 4 + (7+1) \div 2$

First parentheses, then multiply/divide, then add:
$3 \times 4 + 8 \div 2 = 12 + 4 = 16$

Step2: Solve $4^2 + 25 \div 5$

First exponent, then divide, then add:
$16 + 5 = 21$

Step3: Solve $(9-5) + 4 \times 8$

First parentheses, then multiply, then add:
$4 + 32 = 36$

Step4: Solve $8 \times 6 \div 4 + 2^2$

First exponent, then multiply/divide left to right, then add:
$48 \div 4 + 4 = 12 + 4 = 16$
