Multiply:
46 x 2=_______
Explanation
Multiplication is a way of adding the same number multiple times. In this case, you are adding the number 46 two times.
To break it down step by step:
1. Start by multiplying the unit digit (6) of 46 by 2.
( 6 × 2 = 12 )
Write down the 2 and carry over the 1 to the next column.
2. Next, multiply the tens digit (4) of 46 by 2.
( 4 × 2 = 8 )
Add the carry-over 1 from the previous step to the product.
( 8 + 1 = 9 )
3. Write down the 9.
Combining the results:
92
So, ( 46 × 2 = 92 )

Multiply: 90 x 3 = ____________
Explanation
When you multiply 90 by 3, follow this pattern:
1. Start by multiplying the units digit (0) of 90 by 3:
( 0 times 3 = 0 )
2. Next, multiply the tens digit (9) of 90 by 3:
( 9 times 3 = 27 )
Combining the results:
( 90 times 3 = 270 )
So, ( 90 times 3 = 270 ).
4.
Multiply: 12 x 5 = _________
Explanation
1. Start by multiplying the units digit (2) of 12 by 5:
(2 times 5 = 10)
2. Next, multiply the tens digit (1) of 12 by 5:
(1 times 5 = 5)
Now, combine the results:
(12 times 5 = 10) (from the units digit) and (5) (from the tens digit).
So, (12 times 5 = 60).

Multiply: 2 x 3 x 5 = _______
Explanation
1. Start by multiplying the first two numbers, 2 and 3:
(2 times 3 = 6)
2. Next, take the result from step 1 and multiply it by 5:
(6 times 5 = 30)
So, (2 times 3 times 5 = 30).
6.
Multiply : 25 x 6 =____________
Explanation
1. Start by multiplying the units digit (5) of 25 by 6:
(5 times 6 = 30)
2. Next, multiply the tens digit (2) of 25 by 6:
(2 times 6 = 12)
Now, combine the results:
(25 times 6 = 30) (from the units digit) and (12) (from the tens digit).
So, (25 times 6 = 150).
7.
Multiply: 3 x 6 x 10 = _______
Explanation
1. Start by multiplying the first two numbers, 3 and 6:
(3 times 6 = 18)
2. Next, take the result from step 1 and multiply it by 10:
(18 times 10 = 180)
So, (3 times 6 times 10 = 180).
8.
Multiply : 4 x 4 x 4 = ____________
Explanation
1. Start by multiplying the first two numbers, 4 and 4:
(4 times 4 = 16)
2. Next, take the result from step 1 and multiply it by 4:
(16 times 4 = 64)
So, (4 times 4 times 4 = 64).
9.
Multiply : 44 x 4 =__________
Explanation
1. Start by multiplying the units digit (4) of 44 by 4:
(4 times 4 = 16)
2. Next, multiply the tens digit (4) of 44 by 4:
(4 times 4 = 16)
Now, combine the results:
(44 times 4 = 160) (from the tens digit) and (16) (from the units digit).
So, (44 times 4 = 176).
10.
Multiply: 3 x 15=_____________
Explanation
1. Start by multiplying the units digit (5) of 15 by 3:
(5 times 3 = 15)
2. Next, multiply the tens digit (1) of 15 by 3:
(1 times 3 = 3)
Now, combine the results:
(15 times 3 = 45).
So, (3 times 15 = 45).
11.
Multiply: 40 x 5 = _____________
Explanation
1. Start by multiplying the units digit (0) of 40 by 5:
(0 times 5 = 0)
2. Next, multiply the tens digit (4) of 40 by 5:
(4 times 5 = 20)
Now, combine the results:
(40 times 5 = 200) (from the tens digit) and (0) (from the units digit).
So, (40 times 5 = 200).
12.
Multiply: 5 x 2 x 5 =________
Explanation
1. Start by multiplying the first two numbers, 5 and 2:
(5 times 2 = 10)
