Multiplication is the repeated addition of the same numoer. Examples: 5x2is5 times 2, that is 2 + 2+ 2+2+ 2 =L0 3x7is3 times 7, that is 7 + 7 +7 =27 A JuArcLE Scese Three monkeys are Heyl Eoch collecting mangoes from a of us hos 3 tree. Another monkey joins them. Now there How mony mongoes cto we are 4 monkeys. hove in oll? All 4 monkeys have the same number of mangoes. The mangoes are equally grouped. 333 o0o Tb3o ftftftttbttt @+@+@+ tr

This is called repeated addition. All the equal groups are added to find the total. As there are four equal groups of 3 mangoes each, we say it as multiply 3 by 4 and write 4 x 3. 'x'. is the sign of multiplication. The number to be multiplied is known as the multiplier. The product is either greater than or equal to the numbers we multiply. These are 6 jokers in 2 groups. We write it as @.@=[-]\"z_-l o'8\"@=@ These are 4 pebbles in 3 groups. We write it as @.8*E=Eo'E\"E=@ These are 5 balloons in 4 groups. We write it as E-E*E*E=[2ol or. @\"8=@

A man there was issuing a token and collecting {10 for every car parked. Abhinav quickly counted the number of cars parked and found out the total money collected by the man' Abhinav found that there are 15 cars in the parking lot and that person at the parking would have collected 15 x 10 = t 150' Count the number of hours you spend every day in your school' Count the number of days you go to school in a week?

Division as Equal Sharing When something is grouped or divided equally, it is called as equal sharing. Samuel has 15 candies. He wants to share them equally amongst his -'e:'li*l-5 friends. He distributes them one by one. He gives 1 candy to each of them. Samuel is left with 10 candies. He gives 1 more candy to each of them. Now Samuel is left with 5 candies. He again gives L candy to each of his 5 friends. Now, he is left with empty bowl, i.e. zero cand ies. Each of his friends gets 3 candies. We write this as 15 divided by 5 is equal to 3. It can also be written as 15 + 5 = 3 '+' is the sign for division.

Division of a 2-digit Number by a l-digit Number -Let us read about some terms used in division. 4 Quotient The number which is to be divided is called dividend. Divisor--4 | 1 5.-Dividend - -The number that diVides the 16 dividend is called the divisor. 0 The result is called the ouotient. -Remainder The leftover, if any, is called the remainder. Short Division Method Example: Divide 12 by 2. Step 1: Write 12+2asgiven. Step 2: Recall the multiplication table of 2. 2x7=2; 2x2=4; 2x3=6; 2x4=8; 2x5=L0; 2x6=12' Step 3: Stop when you reach 12. Step 4: Write 12 below 12, and subtract. Long Division Method Quotient = 6 Example: Divide 48 by 4. -_t[2i Step 1: Write 48 + 4 as given. 4=tStep 2: Divide the tens digit by the divisor. Recall 4 x 1 = 4 or 4+ Write 1 in the quotient column just above 4, that is, in the tens place. Now, write 4 below 4 and then subtract. -88 Bring down 8. Step 3: Divide the ones column by the divisor. Recall 4 x 2 = 8 or8 +4=2. Write 2 in the quotient column just above 8, that is, in the ones place. Now, write 8 below 8 and then subt Thus,48+4=L2 1.

Write 1 in the quotient in the tens column and 4 below 5. Subtract,5-4=1. 1,6 2:Step Bring down 6 ones. - I6 Now we have L ten and 6 ones = -.' 16 ones. 4 goes into 16, exactly four times. Write 4 in the quotient in the Thus, 56 + 4 = 14 (Quotient) and ones column. 0 (Remainder) Here, the quotient is 14 and the remainder is 0.

Expanded Form We know that the number 685 has 6 hundreds, 8 tens, and 5 ones' rEEI685 = 6 hundreds + 8 tens+ 5 ones =600+80+5 68 600 + 80 + 5 is the expanded form of 685. 685 is called the standard or short form. Example: Write 438 in the expanded form. 438 = 4hundreds + 3 tens + 8 ones = 400 + 30 + 8 Thus, 400 + 30 + 8 is the expanded form of 438.
