(10+9)+(1−1)+(2−2)+(3−1)+(4−4) = 21
This is the same equation rewritten: (10+9)+(3−1) = 21
This can be done as 1-1, 2-2, 4-4 cancel themselves out.
2/5 plus 1/5 minus 3/10 is equal to 0.3 or 3/10
4
2 minus 2/5 plus 1/2 minus 4 = -1.9
The answer is 0.

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
27. 2+7=9 then minus 4. Next is plus 8 minus 3. Plus 9 minus 2. Plus 10 (27). Next is minus 1 which would be 26.
2/5 plus 1/5 minus 3/10 is equal to 0.3 or 3/10
The result of the expression 5 multiplied by 3, divided by 2, plus 4, minus 1 is 10.
