How do you write an expression that can be used to multiply 6 times 198 mentally?
To multiply 6 times 198 mentally, you can break down 198 into smaller, more manageable parts. For instance, you can express it as ( 198 = 200 - 2 ). Then, rewrite the expression as ( 6 \times 198 = 6 \times (200 - 2) ), which simplifies to ( 6 \times 200 - 6 \times 2 ). This gives you ( 1200 - 12 = 1188 ), making it easier to calculate mentally.
What expression that can be used to multiply 6 times 198 mentally?
To multiply 6 times 198 mentally, you can break down 198 into 200 - 2. Then, use the distributive property: 6 × 198 = 6 × (200 - 2) = (6 × 200) - (6 × 2) = 1200 - 12 = 1188. This approach simplifies the calculation by using easier numbers to multiply.
Why expression could be used to multiply 6 and times 198 mentally?
To multiply 6 by 198 mentally, you can use the distributive property by breaking down 198 into simpler components, such as 200 and -2. You can then calculate 6 × 200, which equals 1200, and 6 × -2, which equals -12. Adding these results together (1200 - 12) gives you 1188, making it easier to arrive at the final answer without complex calculations.
