20+30+40+50+60+70+80 = 350
Or (2+3+4+5+6+7+8)×10 = 350
I'm not quite sure what 'pattern' means?
Add by 10 each time.
10 + 10 + 20 + 20 +20 = 80.
1000 + 1000 + 1000 + 1000 + 40 + 30 + 20 + 10 = 4100
Any of them. To get 50 to 30 you could... subtract 20 add -20 divide by 5/3 multiply by 3/5
The factor pairs of 30 are (30,1)(15,2)(10,3)(6,5) None of them add up to 20.
Add by 10 each time.
10 + 10 + 20 + 20 +20 = 80.
Its 30 duhh.. go use a calculator instead govna
The correct answer is: 1000+40+1000+30+1000+20+1000+10 = 4100
40 (+20, -10, +30 ,-20)
This is a Trick question, if you look hard enough. The answer of your question is 4100. When you calculate it in your head, or use a calculator, You get 4100. Look closely. The answer is not 5000. There are 4 1000's. However, 30 + 20 + 40 + 10 ≠ 1000. Your answer is 4100.
170
1000 + 1000 + 1000 + 1000 + 40 + 30 + 20 + 10 = 4100
When multiplying with zeros you just remove the zeros and multiply the other digits then add the amount of zeros you removed to the answer. 30 x 20 = 3x2 =6 then add two decimal to the right with zeros. 600 30 x 20 = 600
The factor pairs of 30 are (30,1)(15,2)(10,3)(6,5) None of them add up to 20.
Any of them. To get 50 to 30 you could... subtract 20 add -20 divide by 5/3 multiply by 3/5
The answer is: 20/2 plus 30 = 40
