There is no need to simplify this, it is only a sum. 21 + (10/2) - 18 = 8
n - 10 + 9n - 3 n + 9n - 10 - 3 10n - 13

(-11) x (-10) + (-20) 110 + (-20) 90
x = 10 Minus 6 times 10 = minus 60 Add 3 to minus 60 = minus 57

10^2 minus 4 times 8 divided by 8 plus 9 is equal to 105.
simplify the square foor of 49 times x to the third time y to the sixth times the absolute value of z squared
In addition and subtraction, if the plus sign is larger than the minus sign, then it's a plus. For example: +10 minus -20 = -10 If the plus sign is smaller than the minus sign, the answer will be a minus. For example: -10 minus + 20 = -10 In multiplication, if you have 2 plus signs, the answer will be a plus sign. If you have 2 minus signs, the answer will be a plus sign then, too. But if you have a plus and a minus sign, then the answer will be a minus. For example: +5 x + 2 = +10 -5 x - 2 = +10 -5 x +2 = -10
