7 - -2 is a minus and a minus
Therefore the answer is 7 + 2 = 9
To calculate (2^7 \times 10^7), first find (2^7), which equals 128. Then, since (10^7) equals 10,000,000, the final result is (128 \times 10,000,000), which equals 1,280,000,000. Thus, (2^7 \times 10^7 = 1,280,000,000).
All numbers less than or equal to 8
To solve the expression 7(2x4), first calculate the multiplication inside the parentheses: 2 x 4 equals 8. Then multiply that result by 7: 7 x 8 equals 56. Therefore, 7(2x4) equals 56.
4x-7=24x=9 x=9/4
3x-1 = 7 3x = 8X= 8/3 = 2+2/3
To solve this expression, we first calculate 7/8 which equals 0.875. Next, we calculate 1/2 which equals 0.5. Finally, we subtract 0.5 from 0.875 to get the answer of 0.375.

It doesn't ! -7 plus -5 equals -12 ! -7 plus 5 equals -2
To solve the expression, first calculate the multiplication: 5 times 4 equals 20. Then, substitute that back into the equation: 2 plus 20 minus 7 plus 2. This simplifies to 2 + 20 = 22, and then 22 - 7 = 15, and finally 15 + 2 equals 17. Therefore, the answer is 17.
