Multiplication with carrying
Multiplication with carrying There are different mathematical operations in math such as addition, subtraction and division. Multiplication is one of the arithmetic operations used in different branches of mathematics. Multiplication is denoted by a cross sign . Multiplication can be used between different types of numbers such as integers, fractions, decimals and many more. Example 1: There are 15 snack-bars in a box. If Ben brought 6 boxes how many snack bars does he have? Solution: Number of snack bar in each box = 15. Number of boxes Ben brought = 6 Total number of snack bars = 15 x 6. Here for the multiplication 6 is multiplied to the ones place 5 x 6 = 30. Carrying the 3 on the tens place. Multiple the tens place 1 x 6 = 6. Now add the carried number to the 6; 6 + 3 = 9. Hence 15 x 6 = 60. Total number of snack bars = 90. Question: Multiple choice question (Pick the correct option.) What is the answer when 56 is multiplied with 4? a) 204 b) 224 c) 2024 d) None of these. Correct answer: option b. Explanation: Here for the multiplication 56 x 4 =? Multiply 4 to the ones place this gives 6 x 4 = 24. (Write the 4 and carry the 2 in 24). Carrying the 2 on the tens place. Multiple the tens place 5 x 4 = 20. Now add the carried number to the 20; 20 + 2 = 22. Hence 56 x 4 = 224.
