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.
To write the expression "4 times the difference of 10 and 8 minus 3," you start by calculating the difference of 10 and 8, which is (10 - 8). Then, you multiply that difference by 4, giving you (4 \times (10 - 8)). Finally, you subtract 3 from that result, resulting in the expression (4 \times (10 - 8) - 3).
To write the expression for doubling 2 and then adding 5, you first multiply 2 by 2, which gives you 4. Then, you add 5 to that result. The full expression can be written as ( (2 \times 2) + 5 ), which simplifies to ( 4 + 5 ), resulting in 9.
The normal way to write z times 19 in an algebraic expression is 19z.
