Complete the pattern by adding 2 each time. 40,\, 42, \, 44, \, ⬚, \, ⬚, \, ⬚
To find out the difference between two numbers, we can jump from our starting number to our target number, like we do in this video.
Find the missing number to equal the number 98.
89 + ⬚ = 98
20 + ⬚ = 98
28 + ⬚ = 98
Sometimes we can solve a problem, and then use that to find a pattern in addition or subtraction. Watch this video to see how.
113+20=133. Use this to find:
113 + 30 = ⬚
113 + 40 = ⬚
113 + 50 = ⬚
