Complete the addition pattern:
+ 10 = 31 + 100 = 310 + 1,000 = 3,100
+ 4 = 7 + 40 = 70 + 400 = 700
+ 10 = 24 + 100 = 240 + 1,000 = 2,400
18 + = 38 180 + = 380 1,800 + = 3,800
+ 5 = 16 + 50 = 160 + 500 = 1,600
+ 7 = 13 + 70 = 130 + 700 = 1,300
4 + = 11 40 + = 110 400 + = 1,100
12 + = 22 120 + = 220 1,200 + = 2,200
+ 4 = 13 + 40 = 130 + 400 = 1,300
+ 7 = 23 + 70 = 230 + 700 = 2,300
25 + = 55 250 + = 550 2,500 + = 5,500
+ 20 = 35 + 200 = 350 + 2,000 = 3,500
+ 7 = 15 + 70 = 150 + 700 = 1,500
+ 6 = 14 + 60 = 140 + 600 = 1,400
+ 7 = 18 + 70 = 180 + 700 = 1,800
6 + = 16 60 + = 160 600 + = 1,600
+ 9 = 20 + 90 = 200 + 900 = 2,000
