Here are the numerical expressions for each problem. Remember to use `/` for division and not leave spaces, as instructed.
1.
Add 6 and 4, then multiply 2
First, add the numbers: $6 + 4$. Then, multiply that result by 2.
Expression: `(6+4)*2`
2.
Add 5 and 10, then divide by 2
First, add the numbers: $5 + 10$. Then, divide that sum by 2.
Expression: `(5+10)/2`
3.
Subtract 8 from 19, then divide by 2
"Subtract 8 from 19" means you start with 19 and take away 8 ($19 - 8$). Then divide by 2.
Expression: `(19-8)/2`
4.
Divide 16 by 2, then add 3
First, do the division: $16 / 2$. Then add 3 to the answer.
Expression: `16/2+3`
5.
3 more than 18 multiplied by 4
First, multiply 18 by 4 ($18 * 4$). "3 more than" means you add 3 to that product.
Expression: `18*4+3`
6.
Subtract 6 from 12, then multiply by 3
Start with 12 and subtract 6 ($12 - 6$). Then multiply the result by 3.
Expression: `(12-6)*3`
7.
Add 9 and 14, then multiply 4
First, add the numbers: $9 + 14$. Then multiply that sum by 4.
Expression: `(9+14)*4`
8.
Divide 90 by 2, then add 27
First, do the division: $90 / 2$. Then add 27 to the answer.
Expression: `90/2+27`
9.
The sum of 12 and 4 multiply by 2
"The sum" means addition ($12 + 4$). You need to find this sum first before multiplying by 2, so use parentheses.
Expression: `(12+4)*2`
10.
The quotient of 16 and 4 plus 2
"The quotient" means division ($16 / 4$). Do this division first, then add 2.
Expression: `16/4+2`
Final Answer:
1. (6+4)*2
2. (5+10)/2
3. (19-8)/2
4. 16/2+3
5. 18*4+3
6. (12-6)*3
7. (9+14)*4
8. 90/2+27
9. (12+4)*2
10. 16/4+2
