10 plus 10 equals 20 20 divide by 10 equals 2 2 plus 10 equals 12
10+2÷(4x3)= 10+2÷ (12)= 12÷(12)= 1
No. It goes in 10 times, with 2 left over. 10 times 12 is 120, plus 2 is 122.

To add (4 \times 10^{10}) and (2 \times 10^{12}), it's helpful to express them with the same exponent. Converting (2 \times 10^{12}) to the same exponent as (4 \times 10^{10}) gives (200 \times 10^{10}). Now, adding them together results in (4 \times 10^{10} + 200 \times 10^{10} = 204 \times 10^{10}), which can also be expressed as (2.04 \times 10^{12}).
12+8+10+12+11+9 = 62
700.
12+14=26+10=36+24=60+10=70+8=78 the answer is 78
20
12 + 10 + 11 equals 33
x=12 . . . as two thirds of 12=8 therefore 8+2=10
